Physical Chemistry

Characterisation of substances

Physicochemical properties, the behavior of substances in different matrices, their capacity to adsorb, dissolve, evaporate, freeze and many others, are essential parameters, allowing the characterisation of a substance or a chemical product.

The Staphyt laboratory can support you in the characterisation of your substances. With each substance being unique, the expertise of our chemists and their knowledge of of the OECD guidelines and other regulations are key to the appropriate selection and application of testing specific to your substance.

Our multidisciplinary teams, in the fields of chemical and physico-chemical analysis, allow the Staphyt laboratory to adapt to the needs of its clients, especially in the scope of tests for REACH, Biocide, Phytopharmaceutical and Pharmaceuticals regulations.
