Description
Areas of activity :
Infra-red and Raman spectrometers can be grouped together under the name of vibrational spectrometry.
As its name suggests, vibrational spectrometry allows probing of vibrational levels to characterise functional groups and the structure of materials. The analysis can be qualitative as well as quantitative.
The use of this technique in the institute mainly relates to qualitative analysis and surface analysis. Moreover, Raman spectrometry is a technique of choice for the analysis of carbon and is widely used for this type of sample.
Main equipment (strengths of the Institute) :
The platform is equipped with 2 FTIR spectrometers and 3 RAMAN spectrometers :
- FTIR spectrometry
- 1 FTIR spectrometer
- 1 FTIR microscope
- 1 PM-IRRAS
- Accessories : Variable angle transmission, ATR, DRIFT, IRRAS
- Raman spectrometry
- 1 Raman spectrometer 532 nm and 632 nm
- 1 Raman spectrometer 244 nm and 488 nm
- 1 FT-Raman spectrometer 1064nm
