Organochlorine Pesticides & PCBs
The concentrations of organochlorine pesticides and polychlorinated biphenyls (PCB) are determined by extracting the sample then analyzing the extract using gas chromatography. The GC is configured with a dual capillary column configuration using electron capture detectors (ECD). Each column is made using different film materials which gives the ability to confirm the presence of any detected compounds.
Method 8081 (Pesticides) and 8082 (PCBs) methods are normally used when analyzing surface and ground water as well as solid sample matrices. Method 608 includes both Pesticides and PCBs and is used for wastewater samples.

4,4'-DDD
4,4'-DDE
