Does anyone have a recommendation for software that will run an FFT on an image to find the REPEATING information (i.e. not remove the repeating noise)? We are collecting information on size and uniformity of arrays - not acutally using it for filtering.
The FFT in Image Pro is for filtering out the repeating information.

We have an old Link (Oxford) eXL computer, monitor, keyboard and mouse for giveaway. It is a parts only deal as we believe the CPU is dead. No detector. Must come and get it or arrange for packing and shipping yourself. Thanks

If you have access to our iTEM software, you can set the filters to either "opaque" (filtering out the periodic structures), or "transparent", which filters out everything BUT the periodic information relating to that specific filter.
Have you checked if you can set this attribute in Image Pro?

You can use Fovea Pro or Image Processing Toolkit, both from John and Chris Russ. Go to their website, http://www.reindeergraphics.com/. It will work in Photoshop and I think Image. On the disc that comes with the software is a complete tutorial on image processing and stereology. It's a good plug-in addition to Photoshop.

We need to produce SEM and TEM images of Campylobacter flagella. Just wondering if anyone has experience with this and has a favorite protocol they might share with us. We have produced good images using uranyl acetate as a negative stain, but we are unsure of the proper buffer, stains, etc., for SEM and TEM that would give us good images of the cells with unbroken flagella. Thanks in advance for your time and trouble.
Dave, Working with a number of different bacteria I have found that for negative staining, fixation prior to staining gives better morphology, something like 2%PF + 2% GA in 0.1 M cacodylate (on the grid after adsorption) for 5-10 min. I also like to use fresh carbon coated grids, no parlodion. This will ensure that you see the flagella and pili with the thin carbon substrate. I have had success with both UA and PTA, remember though no phosphate when using UA to avoid precipitants. As for SEM it is difficult to avoid breakage of thin structures like membrane attachments and flagella, caused by dehydration. Perhaps a non-flexible substrate like silica chips or coverslips would be better than say formvar coated grids. Also you can try a chemical alternative to critical point drying like HMDS. Good Luck.

Does anyone have experience freezing 4489 TEM film for long-term storage? I have stored many types of film at -20C with no problems, but haven't tried it with 4489. Can this cause condensation or other problems?

We have had no problems feezing 4489 film at our school for long periods of time. Sometimes for several years. There has never been any problem with condensation.

The votes are in and here's the partial summary of what people use to calibrate their TEM: My informal survey is based on 24 responses: 63% (14 people) use a grating replica, 68% (15 people) use crystal spacing.
26% of the respondents indicated they use a commercial product called Mag*I*Cal.
For more details and a little verbiage visit Microscopy Society of Northeastern Ohio Blog at: http://www.msneo.org/2007/08/scales-and-distance.html (my face will be really red, if this link doesn’t work!) You can also find what I think is the most unique TEM calibration I've ever read.

Hi Pat, I may have missed that note, our server somehow misplaces things. I checked on Mag*I*Cal and you are correct. NIST doesn't calibrate " fundamental constants of nature." Seems a shame.
Thanks for the note!
Enjoy the week-end!

Frank, I think that there was a correction by the microscopist who gave the message about the NIST traceability. If I remember correctly he wrote "now" and corrected it to "not".

LM and imaging folk--we have a first-generation zeiss axioskop that we've just set up with a scion digital camera and diagnostic instruments coupler for transmitted-light photomicrography. The illuminated field is hideously uneven, with a central hot-spot. The Scion doesn't do shading correction, so, aside from flat-field correction in ImageJ, has anyone else experienced/solved this problem? Will a diffuser in the beam path help?

The workshop focuses on electromechanical coupling in inorganic and macromolecular materials and biological systems and will feature invited tutorials on emergent phenomena in nanoscale ferroelectrics and ferroelectric surfaces, polarization-mediated surface phenomena in polar materials, and piezoelectricity and electrophysiology of biosystems. The central theme of the workshop - Piezoresponse Force Microscopy - will be discussed in a series of tutorials by S.V. Kalinin (ORNL) and A. Gruverman (UNL), that will introduce basic principles of PFM operation, relevant instrumental aspects, and recent advances in PFM imaging of switching ferroelectric films and nanostructures, biological materials and macromolecular systems, and PFM in liquid and ultra high vacuum environment. The tutorials will be complemented by a poster session.
The 2 day workshop will be followed by 3 days of experimental demonstrations of PFM, Switching Spectroscopy PFM, and band-excitation PFM by CNMS staff members and Asylum Research representatives, held in parallel with the CNMS user meeting (October 10-12). The participants are welcome to bring their own samples. The workshop abstract and outline are available on line at http://cnms.ornl.gov/workshops/CNMS_PFM_Workshop.pdf. The registration information will be available shortly at http://neutrons.ornl.gov/workshops/users2007/
The invited speakers include:
M. Gregg (U. Belfast), "Nanoscale Ferroelectrics: Where Size Really Does Matter"
S. Streiffer (Argonne National Lab.), "Phase transitions, domain structure & dynamics, and surface chemistry in ferroelectrics studied by x-rays"
Andrew M. Rappe (University of Pennsylvania), "First-principles and multiscale modeling of ferroelectrics"
Andrew Marino (LSU), "Electromechanics of biosystems"

Please forgive me for using the list to try and solve a personal problem, but I cannot obtain an answer to my question by the official route, so I send this message in a bottle in the hope that some personality involved in the conference will read it and answer it.
I simply would like to know the subjects of the different workshops planned during the conference.
Regards,
Stephane

Title-Subject: [Filtered] SEM_S570_1
Question: I have an old Hitachi SEM, S-570 with a digital photocamera NikonD100 attached to the camera unit. At the observation CRT the SEM-images are sharp while at the CCD the images are not sharp at different camera positions. I checked the CCD camera as I took pictures directly from the observation CRT, and the pictures are sharp. I think that something is wrong with the justage or quality of the photo CRT. Does anybody know, how can I overcome my problem?
First thing to do, if you possibly can, is to check the quality of the photo CRT by shooting some conventional film (say Polaroid). This is fairly important since it will tell you if its a problem with the photo CRT.
Is this the first time setting up the 570 with a digital camera or was it working fine and then became unsharp?
We have a Hitachi S2460N to which I attached a Nikon D70S digital camera. It works fine but one must be very careful setting the camera focus on the CRT is critical. Is it possible that the camera is slipping out of focus (loose components)?

Question: Hi all, would anyone have a manual for the thickness coater complete with circuit diagrams, I need to carry out a fix on one of these devices, thanks, David.
I am looking for a double tilt holder for a JEOL 200CX TEM. OEM or Gatan is fine, I'm not picky.
If you know of any out there please let me know.
Thanks,
Tom

I am having a too strong signal in EDX (in SEM). The dead time is usually between 70-80%. I wondered how I could reduce the signal without changing the HT. Changing the size of the beam is one way. Would it be wise to move the stage in the Z axis to be sub-optimal with respect to the EDX detector? Any other idea?

Dear Stephane, It is not a good idea to move the Z axis of the SEM stage for EDX, this will upset the geometry of the beam-detector system and affect quantitation. There are three possibilities: get an SDD detector, which is much more tolerant of high beam currents, use a higher condenser lens setting (smaller beam spot size) or a smaller final aperture, if your SEM has a movable final aperture. You could also move the EDX detector back along its track (retract it), which will change the solid angle but not the geometry. You may have to re-enter the geometry in the EDX setup if you do that. If you change the HT of the SEM, you may not detect all the elements. Good luck,

Thank you Mary (and Austin too and all the others) for your valuable opinion. As someone pointed out, when I decrease the beam size my signal immediately disappears under the noise in BSE(i am at step 2 on a scale of 20). As for the "time constant", I think on my SEM (it is a Tescan) it is called "process time", I will check this parameter but I don't think it will change much, I must keep it quite high otherwise I lose the resolution of the peaks (high process time=high dead time, lower counts and better resolution). However it is probably the main parameter I'll be able to modify.
I cannot change the apertures.
I could retract the detector, but it is immmobilized in this position and I do not dare to do it. What do you mean by "reenter the geometry of the EDX setup"? Do you mean make a new calibration?
regards,
Stephane

Title-Subject: [Filtered] Beetle Cuticle for TEM
Question: I am attempting to examine beetle cuticle (the wing cover) by TEM but with limited success. In past efforts, I fixed the cuticle overnight in 2.5% glutaraldehyde in sodium cacodylate buffer and post-fixed it in 0.5% osmium tetroxide for 2 hours. Following a standard dehydration in acetone, I slowly infiltrated in Spurr's over the course of a week to ensure full penetration of the resin into the cuticle. I was able to obtain ultrathin sections, but I could not get them to completely flatten. I used both chloroform vapors and a heat pen, but neither would flatten the sections completely.
I know that insect cuticle has a very elastic protein called resilin. I've heard of people dissolving protein from the cuticle by using a KOH solution. I thought that removing this protein could resolve the wrinkle problem, but I am concerned that it would disrupt the ultrastructure.
I was wondering if anyone has had any experience with processing insect cuticle for the TEM and if they could offer any suggestions.
Any feedback would be greatly appreciated!
Sincerely,
Shannon Modla Research Associate Delaware Biotechnology Institute, BioImaging Center 15 Innovation Way Newark, DE 19711

Title-Subject: [Filtered] Epoxy in ultra-high vacuum TEM
Question: We are occasionally using Epoxy Bond 110 and sometimes M-Bond 610 to prepare samples and to attach wedge-polished sections to TEM grids. After following the prescribed time and temperature curves for curing, we ion mill and image in an ultra-high vacuum, high resolution TEM. We have more beam contamination on wedge-polished samples than on FIB prepared samples (our most usual method of sample prep), and there is a small, but noticable degredation in vacuum for about a week after imaging wedge-polished samples. We are thinking the contamination and vacuum degredation may be due to an incomplete cure of the epoxy.
Has anyone else had experience with having to adjust adhesive cure times for ultra-high vacuum TEM work? Does anyone have a recommendation for an epoxy that may cure more throughly and cause less contamination? Also, we have always assumed that using as little epoxy as possible is a good thing, but is there a minimum volume necessary for the initiation of cross-linking during the cure?

Title-Subject: [Filtered] Thin film thickness measurement by SEM/EDX
Question: Dear listeners,
I am trying to measure the thickness of Mo film (about 100nm) on Si substrate by SEM/EDX and Wincasino simulation. From my understanding, Wincasino can simulate a calibration curve of film thickness vs. the x-ray peak ratio of Mo/Si with the same parameters used in experiment (beam energy, TOA, etc.). The real thickness can be located on the calibration curve based on the experimentally measured Mo/Si ratio. It supposed to be an accurate method but I have two questions:
1. Is this method sensitive to the experiment settings (beam energy) and how accurate is it?
2. In Wincasino, which x-ray intensity can be used for peak ratio calculation, absorbed or non-absorbed intensity, or the difference of them? I tried some measurements but they are not promising.
Please also correct me if the procedure I described is wrong.
Dear Teresa, My experience in studying contamination in the SEM was that the contamination was bad for three days after the electron beam hit and "burned" or vapourized the epoxy around a sample. I don't think it was incomplete cure, just that the energy of the beam was high enough to disintegrate the epoxy and put the carbonaceous vapour all through the chamber vacuum. Using as small an amount as possible and keeping the epoxy away from the beam would be my suggestion. Also, you need to mix enough of the components to get the ratios correct and to allow thorough mixing. I find most of my epoxy failures are because of inaccurate ratios or less that complete mixing. Good luck.

Xiaohu, If you only need thickness (not composition), this thickness is perfect for x-ray reflectivity measurements and is very accurate because it looks at the constructive/destructive interference pattern. john

Be careful interpreting the results. Microanalytical experiments like this measure the mass-thickness not the thickness. If you believe you know the density of your film then you are ok and you can then calculate the thickness. If the film density is different from you assumed density (often bulk densities) then you may run into problems.

If I may ask a question, why do you want to measure film thickness using EDX when you can simply take a cross-section and image it? It seems like a long route to the answer, and it won't be very reliable for all the reasons stated on the list. Is this just an experiment or do you plan on using EDX as a method for process control of some kind?

Title-Subject: [Filtered] Measuring Film Thickness With EDX
Question: Question: Dear listeners, } } I am trying to measure the thickness of Mo film (about 100nm) on Si } substrate by SEM/EDX and Wincasino simulation.

The real thickness can be located on the } calibration curve based on the experimentally measured Mo/Si ratio. } It supposed to be an accurate method but I have two questions: } } 1. Is this method sensitive to the experiment settings (beam energy) } and how accurate is it? } } 2. In Wincasino, which x-ray intensity can be used for peak ratio } calculation, absorbed or non-absorbed intensity, or the difference of } them?

Teresa, I have not used the Epoxy Bond 110. I have used the M-Bond 610 and I don't like it for a number of reasons, but primarily because of its shelf life and the need to be refrigerated. I prefer the Epoxy Technology EpoTek 353ND (www.epotek.com). My trick to make sure that my cross sections are completely cured is to put a drop of epoxy on each Teflon® jaw of my vise that I place on my hot plate. When the drop hardens, I put another drop on the other end of the jaws and wait for those to harden. Then I know that the epoxy that I used is fully cured. It takes longer, but I absolutely know that it is cured.
I suspect that you are right and that you are not getting a full cure. I can't imagine that there is enough material that you expose to the beam to cause a noticeable degradation of the vacuum. Besides, the beam would have a tendency to polymerize anything that it hits into a carbonaceous junk.

I've got the JSM-35 put together, but I have one last component to connect. It is a "JEOL Beam Interceptor" made by Krisel Control, Inc. It is a digital picoammeter which connects to a black solenoid that inserts a Faraday cup directly under the beam to measure beam current. It has three connectors on the back, labeled "J1-Power" "J2- Beam Current" and "J3- Sample Current."
I have a cable that goes to the J2-Beam Current connector, and this cable goes to a small box with a switch on it, which in turn connects to the solenoid and Faraday cup. Can anyone tell me where the power cable connects to? I have a bunch of the blue "Stick and twist" cable connectors that I can make a cable with, but I need to know where to get the power from, or at least what voltage to use.
The "Sample current" plug is actually using four wires, so I'm not entirely sure how to convert that to connect to the insulated plug on the outside of the chamber door. Again, a pinout or reference would be greatly appreciated.
Thank you,
Justin A. Kraft

Title: Light microscope/digital image
Question: I have over the past couple of years amassed a AO Series 10 phase contrast microscope that gives a great image. I would like to hook it up to a digital camera (I have a triocular head) and be able to download images to my PC. I am an aquatic ecologist and interested in images of aquatic microorganisms. I am at a loss as to what kind, resolution, manufacturer to approach for the digital camera. I want to spend no more than 2 to 3 hundred dollars for the camera an software. Any recommendations, any articles that might help me decide?
There was a serious electrical fire in rooms adjacent to our laboratory. None of our equipment was damaged by heat, water, powder or foam, but many of our electrical and optical components ranging from high end lasers to microscopes and cameras etc. were essentially submerged in a sea of smoke, fumes and soot to varying degrees.
If anybody has personal experience with this, would you please email me off-list or could we please set up a telephone call to discuss how you dealt with this problem.
Thank you.
-Michael

When this happened to one of our labs we called the equipment manufacturers, arranged to ship the stuff back to them and they cleaned up the internals. It seemed that it was a standard procedure for them. A particular concern was that smoke/soot deposits might lead to electrical short circuits.

We freeze 4489 all the time. Been doing it for decades with out a problem. Have not noticed any issues with any of the "Re- formulations" (that are sensitive to developing issues). As for condensation the 4489 comes vacuum packed in mylar bags (50/sheets per package), allow them to come to room temp before opening (Completely including the middle of the stack not just the surfaces).
(Remember 4489 must be developed with gas burst agitation).

Title-Subject: [Filtered] Secondary electron yield detection
Question: Hello Listeners,
Here I want to in-situ monitor the secondary electron yield under e-beam irradiation. Could anybody recommend one such SE detector or instrument with such function? Another question is what the extent of gas pressure change (say, changes from 10E-6 to 10E-8mbar) affects SE yield and the detector readings. Thank you.

I have begun to build a database of examples for use in teaching TEM and STEM. This project grew out of my need for classroom and homework examples from techniques that I do not employ in my own research. My hobby-horse that TEM measurements should be treated as data, not just pictures, left me unsatisfied with scanning images out of journals, and the result is now on the web at
http://tem.msae.wisc.edu/emdb/
Please take a look. The coverage at the moment is limited to materials-oriented TEM and STEM, since those are my areas of expertise, and remains spotty even within that realm. I therefor also appeal for contributions to the database, especially interesting EDS spectra and diffraction contrast images of crystal defects. For those of you in the US, this is an easy way to leverage "broader impact" from your NSF-funded research: simply send me an interesting but unpublished example from your research. Instructions on how to contribute are on the web site under "About EMdb".
When you access the database, you will be asked for your email address. This is used only as an easy-to-remember unique identifier so that I can do some rudimentary tracking of the database use for the purpose of reporting to NSF.
Please direct any questions, comments, and contributions to me.
Best wishes, Paul Voyles

Nanotechnology Research Spurs Growth in the Global Microscopes Market Source:PRNewswire Author:n/a
Global consulting firm Frost & Sullivan has released new analysis indicating that nanotechnology applications in bioscience and material science research are likely to increase demand for microscopic imaging and analysis systems and contribute to a rise in the global microscope market's revenues from US$1.87 billion in 2006 to US$3.54 billion in 2013. Frost & Sullivan research analyst Lakshman Koundinya said: "With the continued miniaturization of semiconductors and electronicproducts, there exists a growing need for easier and more accurate material inspection. Consequently, there has been a significant increase in funds allocated for research into fields such as nanotechnology and nanosciences, thereby creating significant demand opportunities for microscopes." The article says growth in the microscope market, however, is limited by a lack of technological innovation and other factors that have resulted in the rise of other analytical techniques. The article also says that high cost of manufacturing and significant research and development investment requirements can create barriers to entry in the microscope market. Koundinya said: "Since financial limitations hamper manufacturers' response to the industry's continued technology advancements, consolidation in certain industries such as the disk drive industry has resulted in fewer manufacturers with high financial stability." The article says that manufacturers must create more user-friendly and easy to operate microscopes in order to compensate for a decline in technical expertise. The article can be viewed online at the link below.

I am looking for a reasonably priced, reasonable quality polarizing microscope to round out my equipment for my class. Right now I have a quote for a Leica DM EP, but I thought I'd ask if anyone has a recommendation on other brands that have relatively good optics.
I am also looking for a reasonable digital camera to use for the purpose of sharing live microscope images via a data projector. Any recommendations on models there would be helpful as well. I've looked into the Kenavision scope cameras, but I've heard that the goose neck stand can be a little unwieldy at times.
I'm trying to get the best balance between budget and quality. I don't want an instrument that is cheaply made (As a good portion of the "school grade" microscopes are) but I don't want to break the bank on a $9K instrument.
Thanks in advance for your recommendations,
Justin A. Kraft

Dear Group: does anyone know somebody up in the Savannah area that would be able to give us a value of two instruments that will be given as a tax donation after viewing the instruments? Currently both instruments are not running. Please contact me ASAP, via email redsponger-at-yahoo.com or call me on my cell (954) 401-4542. Thanks so much,

have a look at Meiji microscopes (japanese brand) and Lumenera Infinitiy cameras. Both have very good quality and the price is mid ranged.

We have done this inexpensively (~$2.00) by buying sheets of polarizing material from Edmunds Scientific. We cut a square that we mount on the condenser, and a circle that we insert somewhere in the light path. You then rotate the condenser polarizer until you get extinction. Unless you want more sophistication, this works quite well for things like crystalline materials and even muscle fibers. It does suck up light though.

We are in need of an uninterrupted power system(UPS) for our high-end Field Emission SEM.
I would appreciate if anyone could suggest a good one with reasonable price. The main purpose of the UPS for us is to keep the SEM running when there is a power outage.

I highly recommend Liebert Nfinity double conversion UPS. These can have redundant conversion modules (4KVA each) and redundant control modules. At a full load of batteries, each unit (I have two identical units) has a backup run time of 288 minutes at 22% load. SEM, EDS, EBSD, other PCs are on one unit. Chiller and air compressor are on another unit.
Loaded, each unit costs about $10K and are well worth it. No sag, no drop outs, no sweat. They can also be monitored via HTTP web browser.

We have an older JEOL 840 SEM with a Kevex Sigma setup that we use to acquire digital images. This system seems to have broken - the images on the compter are distorted and noisy, so we want to replace it. Do any of you have opinions as to what system we should get (or not)? We just need digital imaging capability on this instrument - we're not looking to get the EDX back up.
Thanks in advance,

Question: Hi All: I am attempting to stain mitochondria from PRP (using CD41 to stain platelets and looking for an efficient stain for the mitos). Any ideas what to use for minimum background and maximum affinity/efficiency?
I wish I could answer your question. I'd like to know myself. Buehler used to make some very nice sets, but I think they stopped making them. I've seen them from time to time come up for auction on ebay. I have also seen some coming out of Bangalore, India that appear to be newly made. I couldn't find them right now looking on google. I have made quite a few for my own use in house, I don't know what kind of facilities you have to do this. It's a fair amount of work, but it depends upon how many alloys you need to have.
Do let me know what you find out.
Good luck.

I would like to ask for your advice on cutting K4M lowicryl and assessing the polymerized blocks. It is my first time to cut lowicryls embedded in low temperature. I embedded drosophila tissue samples using the supplier's recommended schedule for low temperature embedding. Samples were fixed in 4% paraformaldehyde, 0.2% glutaraldehyde in 0.1M Phosphate buffer, dehydrated in progressive lowering of temperature (PLT) in ethanol, infiltrated and embedded with monostep K4M lowicryl. The resin and sample were cured in a commercial UV cryochamber at -35 degree celsius.
The blocks are hard but I noticed during trimming with a razor blade that it is softer than what I usually deal with in Epon sections. In resin areas close to the trimmed pyramid block face, I can see a slight indentation left after pressing my nail on the resin. I was able to cut 1.2 micron thick sections although it compressed at some areas and later flattened out. The color of the thick sections is not uniform throughout. I get pink, green colors randomly throughout the sections. When I tried to collect thin sections, the sections come with horizontal shreds and do not get a full section. I tried to cut 50-100 nm at 5mm/s then to 2mm/s hoping I could get a full section with these softer blocks. The water in the trough is low enough that kept the diamond knife edge wet. A few times I got water on the block surface, wicked it off with kimwipe and proceeded in sectioning.
Is there a way to make the polymerized blocks harder? When a drop of water got in contact with the trimmed block face, is it necessary to dry it by putting in dessicator before sectioning? I plan on using this resin in the near future with PLT dehydration and UV cryopolymerization. I would like to hear your suggestions to have better sectioning next time.
I look forward to your helpful advice.
Thank you for the time to read my email.
Sincerely,
Claire

Within days of the posting, I received a call from Gatan to help me diagnose the malfunction. A flex cable between the CCD and the camera head electronics was probably cracked such that connection was open only when the camera was inserted and the cable was stretched. This cable is part of the carrier module that slides back and forth holding the CCD. Gatan will actually sell this module (about $3K) for field replacement by the user. But with no other means to further diagnose this 12-yr old camera, I opted to send the camera back to Gatan for repair. I have the camera back this past friday and it's performing fine.
According to Gatan, this flex cable should last about 7 years or so and that certainly will depend on how often the camera is inserted and retracted. If anybody is interested in seeing the inside of this camera, I have some pictures that I can put up on our website. Thanks for all who offered help and advice.

Late but hoping not too late ! I come back from holliday...
A way to "glue" without carbon which has not been cited, is to use as substrate an Indium foil. In is very soft, and one can press the powder in the In film. In is conductive too, if not oxyded. Depending of the grain size of the powder, one may have overlapping from In-L lines with elements from the samples such as Ca-K, but for a carbon search, it should work. It's a way much used in XPS analysis of powders, in UHV environement, where glue outgas to much.
And as In is expensive, it's easy to save monney by re-melt it (in a glas tube) to purify it and separate the last used powder, and laminate it again.
Hope it helps

Title-Subject: [Filtered] estimate roughness of HREM images
Question: Dear All
Could anyone tell me how to estimate the roughness of epitaxial layers by MBE growth like the roughness between Fe and MgO,from both HREM images and ADF images?
There are two main concerns. 1. From HREM, it's hard to see the where is the interface sometime. 2. Because the layer are epitaxial, how to estimate several Amstrong roughness?
The Microscopy Core Facility I am directing is heavily funded by a couple of NIH institutional grants. As a result, I am able to keep most of my microscopes updated and people pay less user fees. I need to, however, to have the PIs acknowledge these grants in their publications.
I keep sending letters to the PIs to request this but without great success. I am sure I am not alone and I wonder how other people/facilities do this?
Thank you for your help.

My first thought upon reading your question was "good luck getting people to acknowledge your facility in their papers", but then I started thinking. Would it work to send a letter out saying that unacknowledged work will be retroactively billed to labs at the 'unsubsidized' (MUCH higher) rate? Just make the case that if they want subsidies they have to help get them.
I don't know if it would work as I have not tried it, but I think I will try it.

I have found that when I ask someone to do something for me that I get more cooperation when I make it easy for them to comply. In your request letter, you might want to include the wording that you would like them to use. In other words, write the acknowledgement for them. You could then suggest that they copy your sentences directly onto their document.

Dear listers, I've spent quite a good deal of time googling for some clues as to how one goes about making a Au on C (also sometimes called gold islands) resolution sample and also an Al/W dendrite sample (which I tried once and didn't seem to get what I was expecting). I couldn't come up with anything about the processes. Does one evaporate or sputter the Au? What type or grade of C is the best substrate? Does one cool the Al/W mixture quickly, slowly, or doesn't it make a difference? I'm going to play with these some, but sometimes it's nice to not have to reinvent the wheel.

Dear Ken, It has been a while since I made these, but I will try to remember. To make the best gold-on-carbon islands, you evaporate pure gold onto polished spectrographic-grade graphite, then post-heat the sample to make the islands coalesce a bit. Takes a few tries to get both the amount of gold and the post heating right. Some of the ones I've seen also have a bit of evaporated tin on top of that; it makes little balls decorating the big balls and is better for a FESEM and high resolution testing. To make the Al-W phase, just put pure Al in a W basket and heat it up until the aluminum melts, then evaporates. Soon after that, the W basket will break at one of the arms, because the Al-W alloy formed is very brittle. The basket with the cooled Al in it will show the dendrites and a pretty Al-W phase. I'm not sure if cooling fast or slow matters, it cools pretty fast when the wire breaks. Good luck,

I once saw a beautiful, albeit unintentional, resolution sample of someone who evaporated gold onto an anthracite coal sample. I thought that the gold on carbon were made by evaporating gold onto a warm polished graphite surface. The gold doesn't wet the carbon and forms islands. If you stop the deposition just before coalescence of the Au islands, you have your resolution sample. Gold has a tendency to films by island coalescence on most substrates. That is why it has a rough structure and is not a good choice for high resolution SEM imaging.
For an alloy that forms a dendritic structure, the microstructure will be finer with a higher cooling rate.

Dear Ken, It has been a while since I made these, but I will try to remember. To make the best gold-on-carbon islands, you evaporate pure gold onto polished spectrographic-grade graphite, then post-heat the sample to make the islands coalesce a bit. Takes a few tries to get both the amount of gold and the post heating right. Some of the ones I've seen also have a bit of evaporated tin on top of that; it makes little balls decorating the big balls and is better for a FESEM and high resolution testing. To make the Al-W phase, just put pure Al in a W basket and heat it up until the aluminum melts, then evaporates. Soon after that, the W basket will break at one of the arms, because the Al-W alloy formed is very brittle. The basket with the cooled Al in it will show the dendrites and a pretty Al-W phase. I'm not sure if cooling fast or slow matters, it cools pretty fast when the wire breaks. Good luck,

Dear listers, I've spent quite a good deal of time googling for some clues as to how one goes about making a Au on C (also sometimes called gold islands) resolution sample and also an Al/W dendrite sample (which I tried once and didn't seem to get what I was expecting). I couldn't come up with anything about the processes. Does one evaporate or sputter the Au? What type or grade of C is the best substrate? Does one cool the Al/W mixture quickly, slowly, or doesn't it make a difference? I'm going to play with these some, but sometimes it's nice to not have to reinvent the wheel.

The free-standing ATF Transformator EA22 110 to 220V step-up transformer required for our Reichert OMU3 ultramicrotome has gone missing and stayed missing sometime in the last year. We know the exact part because we have 2 OMU3 instruments, and only one is now missing the transformer. Does anyone have one they might sell us, or have experience with a serviceable replacement? -- -mike reedy-

Question: Dear list,
Does anyone have any thin crystals of vermiculite suitable for electron microscopy that they might be willing to lend? Also, does anyone know which type of vermiculite is the most beam insensitive (or which types are beam sensitive)?
I am looking for a beam insensitive thin crystal and have found a few papers using vermiculite, but if anyone has suggestions of other beam insensitive thin crystals, possibly with larger unit cells, I would appreciate these also.
Thanks,

Title-Subject: [Filtered] TEM--any concerns while pregnant?
Question: Greetings,
A graduate student, I'm a frequent user on the Jeol 2010 and 1230 TEMs at the university. I also found out that I'm 2 months pregnant. Should I be concern of any x-ray or other ionizing energy that may leak from the TEMs? Should I wait after the first trimester (a few more weeks) to get back on the TEM? Does anybody have any good information or advice?
I will post soon a summary of all the interesting answers I got for the problem of carbon-free preparation of samples for SEM-EDX (not a lot of solution, though).
Now I face a pretty stupid problem that my pair of neurons can't resolve. When I perform an EDX analysis in SEM (Oxford Instrument's INCA software), I obtain 2 values for each peak: weight % and atom %. I guess that weight % represents the integration of each peak area, whereas atom% represents weight%/atomic weight. Now the 2 values can significantly differ, and thus the element ratio of my samples can also be significantly different. And that is precisely what I want to know!
Now, please allow to ask some questions:
- why is the integration of the peaks in the EDX spectrum called "weight %"? - Does the intensity if the peaks in EDX depend on the atomic weight? In other words, do heavier elements produce more x-rays than lighter elements? It is a hard for me to believe this, because electron shells are the same for light and heavy elements (a K shell is a K shell), however it is the only reason I can see to calculate an atom% value. - Which one of the 2 values to use, in which case and why?
Thank you in advance.
Stephane

I inadvertently made a Al/W dendrite sample by heating Al foil (or wire, I don't remember) in a W coil basket in my vacuum evaporator when making a telescope mirror. The Al embrittles the W and as you evaporate the Al, eventually the W wire breaks and you are left with a glob of Al in the basket. Looks great in BSE mode. Henk **************************************************************************** ***
I have made the Al-W dendritic structures in an evaporator. From my observations; 1. Use excess Al for the charge. 2. Heat the charge until the Al is molten. I usually cut-back on heating power, you need just enough to keep the Al molten for about 3 minutes, without evaporating it all away. 3. Cool the molten blob rapidly by just shutting off the heater power. 4. The dendritic structures are located in small "pockets" near the top of the now solidified blob. Joseph M.

I don't know the answer to your question but as far as dendritic grow is concerned, here is what I do know...
Dendritic growth is a process where one constituent of an alloy begins to solidfy before another. This leaves the liquid with a compostion lower in the first constituent and higher in the second. The process of the growing is limited by a diffusion process of the two components in the liquid. This means you get smaller dendrites with faster cooling rates and larger dendrites with slower cooling rates. However, if you cool fast enough, you can't get the diffusion process happening, and so then you don't get any dendritic growth. If you cool really slow, well, then it depends upon the alloy....
You have asked about Al/W. Now those two have really different melting points so I'd think you'd get darned good dentritic growth with those two just about no matter how you cooled it... If you went slow, I'd bet you'd get a lot of interdendritic shrinkage cavities though....
Also, I don't know how big of a structure you want, but it would be my guess that you could cool that alloy pretty quick and have some nice dendritic growth...
What did you do the first time you tried that? And how did it turn out?
If someone does answer you with a lot more info, I'd like to find out myself...If you don't mind sending along the info..

It has been a while since I made these, but I will try to remember. To make the best gold-on-carbon islands, you evaporate pure gold onto polished spectrographic-grade graphite, then post-heat the sample to make the islands coalesce a bit. Takes a few tries to get both the amount of gold and the post heating right. Some of the ones I've seen also have a bit of evaporated tin on top of that; it makes little balls decorating the big balls and is better for a FESEM and high resolution testing. To make the Al-W phase, just put pure Al in a W basket and heat it up until the aluminum melts, then evaporates. Soon after that, the W basket will break at one of the arms, because the Al-W alloy formed is very brittle. The basket with the cooled Al in it will show the dendrites and a pretty Al-W phase. I'm not sure if cooling fast or slow matters, it cools pretty fast when the wire breaks. Good luck,
Mary Fletcher **************************************************************************** **
I once saw a beautiful, albeit unintentional, resolution sample of someone who evaporated gold onto an anthracite coal sample. I thought that the gold on carbon were made by evaporating gold onto a warm polished graphite surface. The gold doesn't wet the carbon and forms islands. If you stop the deposition just before coalescence of the Au islands, you have your resolution sample. Gold has a tendency to films by island coalescence on most substrates. That is why it has a rough structure and is not a good choice for high resolution SEM imaging.
For an alloy that forms a dendritic structure, the microstructure will be finer with a higher cooling rate.

I have been requested to look at a medical item surgically removed from a (living) person and need to determine whether or not to accept this job. Being a materials person, I am quite unexperienced at biological issues. What are some considerations to be aware of to help me decide if this job is appropriate for us or not? I don't know how (or if) it has been cleaned so far, but I've been told that I won't be allowed to do anything to it other than examine it. Sorry, but at this time I can not be more specific.
I have already gotten some valuable and much appreciated input from one local member, but thought I would pose this to the larger community as well.
As always, TIA.

I don't think one can reliably distinguish calcite and aragonite using BSE alone unless their morphologies are diagnostic. On the other hand, distinguishing dolomite should be possible because it has about 20% MgO.
The mean atomic numbers for calcite and aragonite are the same, and both have a backscatter coefficient of about 0.142. Dolomite, though, is less dense and has a backscatter coefficient of about 0.124, so it should appear darker than calcite and aragonite.
This does not mean that there will be absolutely no contrast difference between calcite and aragonite -- it simply will not be clear which mineral is which, though. Both minerals can have various impurities (Mn, Mg, Fe, etc) and crystal orientations that will add variation to the backscatter signal.
As I mentioned, you might have to rely on their morphologies if you're working only with BSE. The crystal lattice of aragonite is different than that of calcite, resulting in different shapes. Aragonite has an orthorhombic system with usually needle-like crystals. Calcite is trigonal-rhombohedral and has a variety of habits: fibrous, granular, lamellar, etc -- more than are easily described here. You can either use the web or consult an introductory textbook on mineralogy or petrography to view examples of the different morphologies of calcite and aragonite.
If the morphologies in your samples don't lend themselves to clearly identifying calcite vs aragonite, you'll have to something like XRD or EBSD to differentiate the crystal lattices.

The first thing I'd do is go to http://www.histonet.org and sign up on the histonet mailing list and post your question. That list is full of people who do this sort of work clinically and in research labs. Including authors of some of the standard histotechnique texts.
Second, check with the people who want to send you the sample and get the details of what they've done and what you can do. At the very least, make certain there was no infection associated with the device or that there is otherwise zero chance of any pathogen coming along with it. Since you're in a materials lab, you will not have any provisions with dealing with any live bacteria/fungi, etc. You should get the sample either fixed, cleaned of biological materials, or if neither, then guaranteed to be healthy. What sorts of microscopy are they looking for? "... won't be allowed to do anything to it other than examine it." really limits what you can do.

Let's assume that you're being asked to look at is either a medical device like a pacemaker or an electrical lead from one or an implant like an artificial joint or tooth filling -- I won't ask you to confirm or deny that -- but that's what I'm assuming for this comment.
We've analyzed such items before (although usually before implantation). Hospitals have strict procedures for anything that doesn't go into the medical waste, usually involving autoclave sterilization. If you are worried about biological hazards or anything like that, you should feel absolutely free to ask the company exactly what has been done to clean it. If it shows up in your laboratory, though, in a biohazard bag, feel free to send it back to them and say "No way." But since medical devices are made to be sterilized before being placed in a human body, they can be cleaned very well, probably cleaner than most other samples.
In the past, we've been assured of cleanliness, and I handle most samples with medical gloves anyway because there are plenty of toxic geological or mat sci samples too. Basically, medical devices can be sterilized -- ask them to do that or find someone else.

The principal axiom of "universal precautions", required for handling human biological material, is to assume that ALL samples are potentially infectious and treat them as such.

Let me address your questions (as I understand them):
} 1: why is the integration of the peaks in the EDX } spectrum called "weight %"?
We have the problem of two uses of the term "weight percent" in X-ray analysis. There is the use of "weight" to describe the relative intensities of the X-ray lines themselves -- that is, the relative intensities of, say, L-alpha and L-beta X-rays -- and this value can be reported as a "weight percent" or coefficient. There is also the use of "weight percent" to refer to the resulting data, calculated in terms of the mass fraction of the elements in a sample. These two uses are creating confusion here. It sounds to me like the software is integrating the area of the peaks to calculate your element concentrations which are being reported in terms of "weight percent" (mass fraction) and "atomic percent" (atom fraction) -- does that make sense with what you're seeing?
} 2; Does the intensity if the peaks in EDX depend on the } atomic weight? In other words, do heavier elements } produce more x-rays than lighter elements?
It is not that simple, and the accelerating voltage how efficiently X- rays are produced from different elements (see "overvoltage ratio"), so it differs at, say, 10 kV and 20 kV. The simple answer is no. The not-so-simple answer involves a lot more than I am willing to type at the moment -- try consulting the section on characteristic X- ray production in Goldstein et al.
} 3; Which one of the 2 values to use, in which case and why?
If you are asking about asking about reporting your results in terms of atomic fraction or mass fraction, that depends on your application or research question and the "standard" format for your field. Why not record or report both? You can also convert data from one form to the other at a later date using Excel and a periodic table. So the answer is "it depends."
I apologize if I've misunderstood any of your questions or problem descriptions.

We have an Oxford system here so I think I can comment on this with authority.
The weight% and atom% labels DEFINITELY refer to the two ways of expressing results.
Weight% is synonymous with mass%. It is only roughly proportional to peak intensity. As Ellery pointed out, there are many things that affect the conversion of raw peak intensity to weight fraction. The only time I make use of the correlation is if I am estimating compositions by eye. A 1 wt% S Ka peak and a 1 wt% Au Ma peak have _roughly_ the same integral where the atomic fractions would be widely different.
Atomic% is synonymous with mole%. It is directly related to weight% by the atomic weight of the species. It can be easily calculated using a spreadsheet; however, every (computerized) EDS system I have seen offers atomic% as an output option.
The two numbers are often widely different, so which do you use? It depends. If you are interested in stoichiometry and formulas, you want atomic fractions. If you are checking a sample against its formulation, the sample was undoubtedly weighed out and you likely want mass fraction. For example, I was working on a sample of EuAl2 for a researcher yesterday. The mole (or atomic) fraction of Eu is 33.3%. However, the mass fraction is 73.8%. Both answers are "right".
Regarding your question of why does intensity depend on weight fraction more than atomic fraction, I would have to dig back into the texts to say for sure. Weight depends (essentially) on the mass of the nucleus and that tells you the number of protons and neutrons and thus the number of electrons. Now whether it is the number of electrons or the mass of the nucleus that determines the x-ray intensity from an atom, I would have to go look. The answer could be a combination of factors.

Hello all,
We have an Hitachi S4500, vintage ~1993. We recently added a digital acquisition & EDX system. The acquisition system sits by idle while you tune up the image (select area, magnification, focus, etc.) on the scope's video monitors, then takes over to acquire the image. Everything works beautifully, but the ergonomics are not very good. We have our PC monitors sitting on top of the console, so they are uncomfortably high to look at.
I would like to simply remove the console CRTs and replace either with a small monitor, or even better, pipe the video signal into an image capture board to display in a window on the acquisition PC. That's where my question lies--how to pull the video signal out. I realize the console has a video out BNC connector which I have tried, but the quality isn't quite there. (Maybe a sync problem? the image is somewhat distorted.) Our electronics guys say the old CRTs are hardwired into the system. Does anyone know if this is a standard video signal? If so, we'll simply remove the old CRTs (replacing the hard-wired connections with a standard connection) and cut down the console, leaving a place for the PC monitors. If there is no standard video signal, then things get substantially more complicated, of course.
Any suggestions or insight would be appreciated.

Dear Elizabeth, I have had various graduate students and technicians working in my lab while pregnant and on my 200 kV Hitachi TEM. The instrument was checked by the university's Radiation Control Officer with a Geiger counter when it was first installed and periodically after, particularly after the gun was disassembled and serviced. The pregnant ladies also wore film badges, which are much more sensitive to accumulated radiation than a Geiger counter. No significant leakage was ever found, in fact, the bricks in the walls turned out to emit more background radiation than the TEM operating at 200kV. Having said that, you can check that the TEM is operating within radiation emission limits by: 1. Having it checked while it is operating normally, with you in the position where you normally operate the TEM 2. Always make sure all apertures, particularly the moveable condenser aperture, are in place before turning on the beam. Let someone else align the beam with the C aperture out, if necessary. I think the modern microscopes are very well shielded and do not leak significant radiation. Regards,

Title-Subject: [Filtered] TEM--any concerns while pregnant?
Question: Greetings,
A graduate student, I'm a frequent user on the Jeol 2010 and 1230 TEMs at the university. I also found out that I'm 2 months pregnant. Should I be concern of any x-ray or other ionizing energy that may leak from the TEMs? Should I wait after the first trimester (a few more weeks) to get back on the TEM? Does anybody have any good information or advice?

Dear Elizabeth, Modern EMs are well-designed so that they emit very little radiation, and the safety officer at your institution should make frequent checks to see that the EM meets the spec. That said, you could wear a dosimeter to measure your exposure. I would hope that you would be reassured that your exposure is minimal--probably below the limit of detection.

Many, many moons ago, I had our TEM surveyed by our radiation safety guys when I was pregnant (JEOL 2000FX) and what they discovered was that there was absolutely no radiation leakage EXCEPT when the condenser aperture was out. Ours has two sets of apertures - top hat and regular and there is an intermediate setting with no aperature in. We tried messing up the centering on the apertures and everything to see if anything leaked and it didn't except as I stated above. I recommend a similar check for you. I'm sure someone on campus at Rice has a detector. I worked at Hanford laboratory and had some extra radiation training and developing cells are very sensitive to radiation. Along the same lines, you need to be very careful about what chemicals and biological hazards you handle when you do sample preparation. We've had lots of female graduate students, employees and faculty pregnant in my 18 years here and I've never had trouble getting people to cover for a pregnant woman. Of course, I'm in the south and southern gentlemen are wonderfully polite so maybe that is why it was so easy for us!! I'm sure there are rules that protect you from being forced to do stuff that is hazardous now if you find out there are issues in your lab. Check with your safety department and congratulations.....

Title-Subject: [Filtered] TEM--any concerns while pregnant?
Question: Greetings,
A graduate student, I'm a frequent user on the Jeol 2010 and 1230 TEMs at the university. I also found out that I'm 2 months pregnant. Should I be concern of any x-ray or other ionizing energy that may leak from the TEMs? Should I wait after the first trimester (a few more weeks) to get back on the TEM? Does anybody have any good information or advice?
I am trying to locate the C.M. Taylor Corporation, specialists in microbeam standards. We were given one of their standards (NO. 202) but need a map of the minerals present. Any help would be appreciated.

Title-Subject: [Filtered] negative staining problem
Question: I believe there was a previous discussion on the List concerning this issue, but I could not locate the subject in the archives. I am having a negative staining problem with what is commonly referred to as 'champagning' or tiny bubble-like areas around specimens and other particles on the grid. I observe this frequently with all stains I use--UA, PTA and amm molybdate--and at different concentrations and pH values. It also doesn't appear to be affected by surfactants or time duration of stain application. I seem to recall this phenomenon is not well understood as to its cause, but I was wondering if anyone may have any information or ideas on how to minimize or eliminate this from occurring. Thanks,
if the electron microscopes are well maintained and have the usual safety checks, there should be no problem during normal operation.
I would be much more concerned about chemical and biohazard risks in the lab, which of course should normally be assessed.
In the UK it would be possible to ask if a risk assessment for the lab would identify specific risks to pregnant women.
Congratulations and I hope all goes well in March/April next year.

Stephane asks ...
} - why is the integration of the peaks in the EDX spectrum } called "weight %"? } - Does the intensity if the peaks in EDX depend on the atomic } weight? In other words, do heavier elements produce more } x-rays than lighter elements? It is a hard for me to believe } this, because electron shells are the same for light and } heavy elements (a K shell is a K shell), however it is the } only reason I can see to calculate an atom% value.
The EPMA technique, whether EDX or WDX, is more sensitive to mass% than atom%. I know this is somewhat counter-intuitive and I remember having the same conceptual problems myself. However, you can do simple tests with stoichometric compounds that include heavy and lighter atomic numbers. A good example would be to compare Fe metal and FeO. If you integrate the Fe Ka peak for both you'll see that for FeO it almost directly calculates the mass fraction rather than the atom fraction.
Therefore mass fractions are always the direct result of EPMA, while atom fractions are calculated secondarily. Most analysts will always report the mass% because it will include the actual total of all elements, while the atom% will always be a result of having normalized to 100%.

My concern is a safety one. We already had one technician who had an adverse reaction to fumes (gloved fingers swelling, numbness) when we tried a similar configuration some years ago. We had the microwave on a table at 90o from the hood so the distance to move samples and chemicals between the two were as short as possible. The microwave vent tube was run into the hood. This technician has not had any adverse reactions since the microwave and all processing is done in the same hood.
I would like to hear from others as to what your feeling are concerning the safety issues involved and what you feel is the appropriate way to deal with these safety issues.

Hi Deb. That microwave should be under a portable hooded enclosure which can be vented to the main hood, with sufficient adjoining work space for reagent handling. Check out the vented bench top workstations from Flow Sciences: http://www.flowsciences.com
Also, you didn't state the protective wear your colleague was wearing. I highly recommend the use of non-powdered Nitrile gloves (double up and discard the outer layer if they become fairly contaminated with resin).

We have similar situation to your original situation. Our main processing microwave sits right next to the hood and is vented through a properly taped duct system. We try to train our clients to always use the vacuum chamber, regardless if they are applying vacuum or not. The chamber can be closed during the transfer from the hood to the microwave.
Our main issue is getting people to clean up after themselves. If anyone has a nice way to convince your clients to clean up after they finish processing I would love to hear it. The usual threats of taking away privileges does not seem to work.

Kenneth- I have never tried this, but I would be surpised if it would work. Lowicrl resin is itself quite reactive, and I would expect it to have reacted with a lot of the primary and secondary amines that OsO4 reacts with. This may be worth a try though. It has never been reported, to my knowledge, so it would be new knowledge. Carol

2 minutes in 2% UA and 30 seconds in lead citrate give strong staining with LR and Lowicryl. This will give negative contrast on membranes and positive contrast of microtubules. Ribosomes stand out very clearly, too.
Also, I would recommend 2% (unbuffered) potassium permanganate for 2 minutes. This will give good positive contrast of membranes. (My experiences are mostly with plant material, however.)
Pre-embedding treatment of tissue with 2% UA overnight before lowicryl will preserve/stabilize the membrane as well as give them some contrast after sectioning.

I have observed gold islands before that resulted from heating gold-coated silica at several hundred degrees (a client's project). Prompted by the current discussion and our own need for such a sample, I decided to go low-tech and try replicating the result with gold on carbon.
I sputtered several garden-variety graphite stubs with about 20 nm of gold and heated the samples in a muffle furnace at about 500 C for about two hours. I was busy with other things and did not control the time well. I also did not experiment with the temperature or the thickness of gold. (I probably should go read Humenansky's note.)
I got decent islands of gold on all samples. I have posted images on our server at ftp://www.marl.iastate.edu/Gold-on-C/. The images were comparable to those from our service engineers gold-on-carbon samples. Now I wonder why I didn't try this sooner.

I have a question for the List. What is Dark Field STEM? I have a student in our department who wants to use Dark Field STEM to image some fibers and use it to calculate mass per unit length. Mass is directly proportional to the density of the fiber. This is in reference to an article by C. S. Goldsbury in 2000. I need help in understanding how this is not just SEM imaging or inverted STEM imaging and in understanding what programs were used to make the measurements and calculations. Any comments and advice would be welcome.
Thanks, Jeannette

We're trying to "resurrect" an old Gatan DuoMill and have a problem. Basically, the back guns on both sides have a "dark current" of ~0.5mA when the voltage is set at 6kV and there is no gas flow. When you introduce gas, you can get a beam that looks almost normal. The front guns appear to work correctly but when you select both guns, the back gun appears to be the only one working. Thus, we're trying to identify the source of the "dark current" as that appears to make milling from both sides impossible. Any veterans with experience on these things with suggestions?
Thanks very much for any suggestions.

Dear Jeanette, Dark field STEM uses a focussed beam rastered across the specimen to produce an image consisting only of scattered electrons. This is realized by having a detector that does not detect the unscattered beam. For example, a small dot of absorbing material can be put in the objective lens back focal plane where the unscattered beam goes, i.e., in the center of the diffraction pattern, and the unabsorbed electrons can continue on to the detector, or a detector with a hole in the center can be placed in a plane conjugate to the diffraction plane. A practical method that can be used with some specimens is to put the objective aperture off-center to block the unscattered beam. This method produces an image that includes only some of the Fourier components, but if the fiber has the same composition along its length, the proportion of the total scattered beam to that which passes through the aperture and is detected will be constant, so relative measurements of the mass per unit length should be OK.

I haven't worked on a DuoMill in a long time, but here are some things that I would look for.
What's the color of the plasma that you can see in the gun? If it is not purple, then you have a vacuum leak. Nitrogen will look pinkish. Nitrogen will ionize much more easily than Ar and if you set it up for both guns, your current will be the one with N2, not the Ar. If it is purple, then you have a short. It might be a carbon track short or a thin film metallization short which will only be seen at a higher voltage. Slowly bring the gun up and see if there is a point where there is a big jump in your current. Your solution there is to take the gun apart and thoroughly clean it, paying particular attention to the ceramics. Any metallization or carburization must be removed or replace the ceramic.

We're trying to "resurrect" an old Gatan DuoMill and have a problem. Basically, the back guns on both sides have a "dark current" of ~0.5mA when the voltage is set at 6kV and there is no gas flow. When you introduce gas, you can get a beam that looks almost normal. The front guns appear to work correctly but when you select both guns, the back gun appears to be the only one working. Thus, we're trying to identify the source of the "dark current" as that appears to make milling from both sides impossible. Any veterans with experience on these things with suggestions?
Thanks very much for any suggestions.

I haven't seen a response to this, but you are way off-base on your assumptions.
The wt% and at.% are simply two ways of expressing compositions. The wt% is typically output because materials scientist will almost universally use wt.% to express phase diagrams. The area under an X-ray peak is called the integrated peak intensity (after the background intensity is subtracted.) All of the X-ray microanalysis techniques for bulk samples have to account for atomic number, density, and fluorescence effects. These corrections correct for the production of X-rays as a function of depth (the phi-rho-z curve), absorption of X-rays as a function of depth, fluorescence as a function of depth. Now all of these corrections depend on the composition. The integrated peak intensities for the elements are used to iteratively calculate the compositions. These calculations in the various correction routines are easier to perform using the wt% values for concentrations. I suggest that you look at the Goldstein et al. book for SEM and Microanalysis.
To calculate the at.% of Fe in FeO is easy. It is 1/(1+1) = 0.5 or 50 at.%. For Fe2O3 it is 2/(2+3)= 0.4 or 40%.
To calculate the wt.%, you need to use the atomic weights of the elements.
For Fe in FeO, you have 1*55.85/(1*55.85+1*16.00) = 0.777 or 77.7 wt.%. For Fe2O3 it is (2*55.85)/(2*55.85 + 3*16.00) = 0.699 or 69.9 wt.%.
Once the software finds the wt%, it uses a relatively simple algorithm to calulate the at.%.
You should check any introductory materials science book having a chapter on phase diagrams to see how it is done.
To answer your third question, they are equivalent. When you do an oxide, doing the oxide by ratio, it is easier to do it by at.%.
Now the other question that you asked is again tied up in the stuff that I said above, but there is another thing that you should be aware of and that is the issue of fluorescence yield. There are two competing physical processes that can occur to relieve the excess energy in an atom when a core electron is ejected from that atom. The first is X-ray emission which you are familiar with. The second is Auger electron emission (After Pierre Auger). Auger electron emission is a two electron emission process. Let's take a K shell excitation example. Just as in the emission of a K-alpha X-ray, an electron from the L shell drops into the K shell, but instead of the excess energy coming off in the form of a an X-ray, the excess energy left is enough to ionize another L shell electron. This would be the emission of a KLL Auger electron. Auger electron spectroscopy if a surface analytical technique since the Auger electrons will loose an indeterminate amount of energy if it is emitted within the bulk of the sample and it is just added to the backscattered electron background. X-rays and Auger are competing processes. The X-ray fluorescence yield is the probability of an X-ray being generated when a core shell electron is ionized. The X-ray fluorescence yield is higher for heavier elements than lighter ones. The auger yield is more prevalent for light elements. This is just another natural physical thing that the analyst is fighting against when doing light element X-ray microanalysis.

Dear listers,
I will post soon a summary of all the interesting answers I got for the problem of carbon-free preparation of samples for SEM-EDX (not a lot of solution, though).
Now I face a pretty stupid problem that my pair of neurons can't resolve. When I perform an EDX analysis in SEM (Oxford Instrument's INCA software), I obtain 2 values for each peak: weight % and atom %. I guess that weight % represents the integration of each peak area, whereas atom% represents weight%/atomic weight. Now the 2 values can significantly differ, and thus the element ratio of my samples can also be significantly different. And that is precisely what I want to know!
Now, please allow to ask some questions:
- why is the integration of the peaks in the EDX spectrum called "weight %"? - Does the intensity if the peaks in EDX depend on the atomic weight? In other words, do heavier elements produce more x-rays than lighter elements? It is a hard for me to believe this, because electron shells are the same for light and heavy elements (a K shell is a K shell), however it is the only reason I can see to calculate an atom% value. - Which one of the 2 values to use, in which case and why?
Thank you in advance.
Stephane

I'm in complete agreement with Scott. Also, you can learn a bit more from any textbooks of Modern Physics.
The Answer to your question at the end is "Yes". The K shell of atom A is different of the K shell of atom B as far as their binding energy is concerned. Also given the fact of the existence of ONE vacancy in the K shell, the probability to generate X-ray photons is deferent from Z1 (element one) to Z2 (element two), so are the energy amount of any individual X-rays dictated by characteristic orbit energy differences.
Please note, when you do quantification, you need to take into consideration of a factor called "ZAF", standing for "atomic number", "absorption", and "florescence". For example, a total integral of a lighter element A peak generally carries more weight than the same total integral of a corresponding heavier element B beak assuming the primary energy of the e-beam is sufficient.
Wt% and at% are equivalent (please find that in any General Chemistry book.)
Yes, reading some more books shall help!
