The objective of the Analytical Chemistry Laboratory Applied to Health (C2AS) is to support research projects in the field of human, environmental and animal health that require expertise in analytical chemistry. The laboratory develops targeted analytical methods for measuring molecules of interest in various biological, environmental and food matrices, and in particular environmental pollutants (pesticides, heavy metals, etc.). C2AS has an analytical platform containing LC-MS/MS, GC-MS/MS and ICP-MS mass spectrometers, which currently enable targeted analysis of molecules of interest.
