title: Isolation of toxic polychlorinated biphenyls by electron donor-acceptor high-performance liquid chromatography on a 2-(1-pyrenyl)ethyldimethylsilylated silica column.
abstract: A rapid and simple liquid chromatographic method for the isolation of toxic planar polychlorinated biphenyls from their formulations by electron donor-acceptor high-performance liquid chromatography using a 2-(1-pyrenyl)ethyldimethylsilylated silica column is described. The separation takes less than 15 min and a complete analysis, including quantitation by gas chromatography-mass spectrometry or gas chromatography with electron-capture detection, may be completed in 60 min. Retention data for 105 individual polychlorinated biphenyl congeners are presented and the retention behaviour, as well as the mechanisms of separation, are discussed.
