Physico-chemical studies

icon Physico-chemical

The physico-chemical properties, the behavior of substances in different matrices, their capacity to adsorb, to dissolve, to evaporate, to freeze and so many others, are essential parameters allowing the characterization of a substance or a chemical product.
We support our customers in the characterization of their substances. Each substance being unique, the expertise of the teams, mastery of the OECD guidelines and knowledge of the various regulations are a major asset in the correct choice and adaptation of the tests to be carried out.

Substances characterization

  • UV – IR Spectrum analysis
  • NMR data interpretation
  • GC-MS or LC-MS or IC spectroscopy
  • High-resolution mass spectrometry
  • Purity analysis
