Spectroscopie FTIR

Page author: Valérie Magnin.

Equipment allowing the analysis of the vibration modes of molecules in the middle infrared (4000 - 400 cm-1) in transmission and attenuated total reflectance (ATR mode with a diamond crystal). The analysis of liquid samples is possible thanks to a specific cell in transmission but also in ATR mode (Ge crystal). The coupling of this spectrometer with our thermogravimetric analyzer (ATG) will allow to follow the gaseous products resulting from the thermal decomposition of various samples by adding a heated gas cell and a heated transfer line that link the two equipments.
