Samples
he JEOL
conductive samples, including organic materials (polymers, etc.), ceramics and glasses, and biological samples.
Sample Holders
Please use clean,
Two different sample holders are available. The smaller sample holder is designed to take 10 mm diameter x 10 mm tall cylindrical sample mounts or other small specimens that fit into the same volume. We have a large number of aluminum cylindrical sample mounts for use with the smaller sample holder. The larger sample holder is approximately 32 mm in diameter x 10 mm tall, and is designed for creative attachment of larger specimens. It’s best if you can fit your samples onto one of the standard sample holders, but if not, other arrangements may be made (talk to Professor Stolk).
Other types of sample holders are available. See Professor Stolk for information on ordering sample holders.
Sample Preparation – Conductive Materials
1.Small samples that fit securely onto one of the standard sample holders are best. Use a precision saw to section larger materials to an appropriate size, if possible.
2.Remove excess lint, dust, moisture, and other debris from your specimen, unless you want to examine those things.
3.Use conductive carbon tape, carbon tabs, carbon paint, or copper tape to attach your sample to a sample holder or cylindrical sample mount. If you use carbon paint, please wait for the paint to dry (or use a heat gun or hair dryer) before you load the sample into the instrument.
4.A sample height approximately even with the top surface of the sample holder is recommended. With tall samples, you risk contacting one of the detectors or other sensitive interior components and causing major problems (and repair bills!).
Sample Preparation – Non-conductive Materials
1.Small samples that fit securely onto one of the standard sample holders are best. Use a precision saw to section larger materials to an appropriate size, if possible.
