ABSTRACT



Polychlorinated biphenyls (PCBs) and chloroorganic insecticides interfere with gas chromatographic analysis, thereby complicating their quantitative determination when multiple compounds are assayed. Perchlorination of the standards of the chlorinated compounds was used to simplify quantitative determination of these contaminants. Results indicate that perchlorination converts PCBs to a single compound (decachlorobiphenyl – DCB) that does not interfere with the assay for chloroorganic insecticides. These data confirm that perchlorination allows for simultaneous testing of both PCBs and chloroorganic insecticides during chromatographic analysis.

Key words: as chromatography; perchlorination, PCB, chloroorganic insecticides.
