Information

Aims, contents and method of the course

Our Scanning Electron Microscopes (SEM) offer various techniques to investigate samples.
In this course you will have the opportunity to learn the necessary preparation steps and the usage of the SEM in several modes so that you can apply these techniques with your own samples afterwards.
The following techniques will be offered for sample preparation:
Fixation (glutaraldehyde, OsO4), dehydration (Ethanol, Acetone, DMP), drying (critical point, chemical), coating with gold and carbon, cryopreparation.
On the SEM you will use the following modes:
Secondary electron detector in low vacuum and high vacuum, backscatter electron detector in low vacuum and high vacuum, energy dispersive x-ray micro analysis with EDX detector (demo), cryo transfer of deep frozen samples (DEMO)
