Department of Analytics - Techniques

Geoscientists at the Helmholtz Institute Freiberg for Resource Technology apply microanalytical methods to solve a wide range of scientific questions. They are used to determine chemical, crystallographic or structural parameters in situ and almost non-destructive at the highest possible lateral resolution.
