For STEM users – Analysis Request forms

I have discontinued the “Intake Sample Request” form.

If you are a certified operator of the FEI Titan STEM, please fill in the “Independent Usage Request” form available through this webpage:

https://www.mtu.edu/acmal/shared-facilities/electron-optics/instrumentation/fei-200kv-titan-themis-s-tem/

If you require staff operated analysis fill in the “Request Analysis” form available through ACMAL webpage https://www.mtu.edu/acmal/

STEM users – O2 sensor in the lab

The O2 meter at the STEM lab is inoperante. We are now using a small hand size backup O2 sensor (see picture) in the STEM lab. It’s on the window stool.

If it reads 24 it means the oxygen level is normal.

Please, do not remove this oxygen sensor out from the lab, and leave it next to the window so it’s visible from outside.

If it flashes and beeps please leave the room and let me know or ACMAL staff know.

Handheld sensor with O2 display reading at 24.

Recommended TEM grid types for different applications

This is a great and useful chart from TedPella (https://www.tedpella.com/) if you want to find out what type of TEM grid works best for your TEM work.

Most of the listed types of substrates are available for ACMAL-STEM users.

Substrates, Support Films for Transmission Electron Microscopy Grids

See the PELCO® TEM Grid Support Film Application Guide.
