Polychlorinated biphenyls (PCB) detection

PCBs are synthetic molecules with specific properties. They have a high thermal conduction power while being electrically insulating and practically non-flammable. These characteristics made them particularly used in electrical transformers and capacitors during the XXth century. Their high toxicity has led to their surveillance and restriction in the industrial environment. The detection and quantification of PCBs is therefore a major industrial and environmental issue.

Thanks to extraction protocols adapted and optimized for all types of matrices, a large range of samples can be analyzed (Soils, liquid effluents, gels, paints, industrial products ...). The sample preparation results in obtaining an extract which concentrates all the PCBs potentially present.
=> The injection of this extract in GCMS then allows detection and quantification of PCBs.
