'The analysis of sludge, sediments and waste is an important component of environmental protection. Analyses allow us to evaluate the quality of these matrices in order to choose the appropriate solution.' 
Bernard Duperron, Environmental Analysis Activity Manager


 Analyse the composition of solid matrices

Our laboratories offer an extended range of analyses of specific chemicals in the Identification and Reduction of Hazardous Substances in Water (RSDE), for samples with a high concentration of TSS. This range of analyses allows for the characterisation of sludge, sediments and waste.
