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 high-level expertise of the Vibrational Spectroscopies Platform allows it to participate in different research projects (FUI INNOVAL, POLYWOOD…) and to provide methods development, analytical services to both public and private research centre.
