Hydrochemistry and contaminants laboratory

The hydrochemistry and contaminants laboratory of the CHYN disposes of a wide range of analytical methods to characterize the general hydrochemical composition of groundwater and the occurrence of organic and inorganic contaminants. The laboratory specializes in particularly in the analysis of stable isotopes in water and organic contaminants using mass spectrometry and laser spectroscopy methods.
