* VARIGATR for surface analysis.
High Temperature / Vacuum Room for Collector II ranging from room temperature to 900 ° C for variable temperature analysis.

Software: OMNIC

Used on reservation for specific analyzes.

Analayis examples

Evolution of the IR spectra at different temperatures.
We can observe the loss of water, then the solvent, and finally the degradation of the product.

These facilties are open to the entire scientific community.
