Determination of congeners of polychlorinated biphenyls in reference materials

Abstract

Abstract Aroclor reference materials from the United States Environmental Protection Agency repository are proposed for use as secondary standards for the congener‐specific analysis of polychlorinated biphenyls in environmental samples. Representative samples of the materials have been analyzed using a gas chromatograph equipped with photo‐ionization and electron capture detectors. The elution pattern of the congeners was determined for a DB‐17 capillary column.
