REAP Raman micro-spectroscopy

The technique
Raman micro-spectrometry analysis is based on the scattering of light by matter (gas, liquid or solid). It is non-destructive and the probe is microscopic. Raman micro-spectrometry is easy to implement, with little or no sample preparation required, making it ideal for use upstream of a chain of analyses (IR, SEM, XRD, ICP-MS, etc.).
Its versatility enables in situ measurements under extreme conditions of pressure (0-100 GPa), temperature (77-2700 K) and tension/compression stress on solid, liquid or gaseous samples, by coupling high-pressure, high-temperature cells to the spectrometers. The laboratory has pioneered the use of Raman under extreme conditions, and the service provides inexperienced users with access and training in these cutting-edge techniques.

How it works
These instruments attract not only INSU researchers, but also solid-state physicists, chemists and biologists. This multidisciplinary approach enables us to develop methods that are transferable to fields ranging from planetology and archaeology to forensics. The use of a portable Raman for field campaigns can be combined with high-resolution spectrometers in the laboratory to characterize samples.

The platform is open to scientific collaborations outside the laboratory. For training, booking or development requests, please contact the platform’s technical manager at raman@geologie-lyon.fr.
