Virtually any sample may be studied by Infrared spectroscopy: liquids, solutions, pastes, powders, films, fibers, gases, and surfaces. Infrared and Raman spectroscopies are analytical methods providing information on the molecular structure of materials.They are related and complementary techniques with a broad scope and several key advantages : non-destructive, requiring few material (<2mg), accessible to all types of samples (liquids, powder, block, deposits, sample within a micrometric scale -Micro FT-IR), achievable on organic and inorganic compounds…
In addition vibrational spectroscopies are used in a wide range of applications :
- Identification of organic compound, mineral or a specific function present in this compound
- Study of surface defects : adherence, color, appearance, pollution on board, reflective surface study …
- Quantification of compound
- Characterization of molecular associations : intra or intermolecular hydrogen bonding
- Study of the order and disorder of matter (state of crystallinity), identification of isomers
- Analysis of the gases resulting from the thermal degradation of a sample (eg polymer) to propose reaction schemes for degradation of material.
- Reaction Understanding : In situ reaction monitoring enables the tracking of concentration changes of key reactive and transient species to understand mechanism pathway, determine kinetics and detect major reaction events for real-time process optimization.
The manager of the Vibrational Spectroscopies facilities participates in different research projects, developps analytical methods and carries out analytical services to both public and private research centre.
