Characterization and determination of PCB isomers by high resolution gas chromatography and HRGC/mass spectrometry

Abstract

Abstract An integrated analytical procedure for polychlorinated biphenyl (PCB) multiresidues in environmental samples has been developed and applied to well‐characterized samples. PCB residues are characterized and quantified using wall coated open tubular column (WCOT) gas chromatography or HRGC/MS‐selected ion monitoring. An automated data system based on a Spectra Physics SP‐4200 computing integrator is used to select and quantitate peaks of individual congeners and homolog groups. This procedure consistently yields results with a reproducibility within 3 percent for HRGC‐ECD and 3.7 percent for HRGC/MS‐SIM technique respectively.
