A multidimensional gas chromatographic technique is suggested as a tool for effective separation of polychlorinated biphenyl (PCB) congeners which cannot be separated on a single SE 54 or other column. Two capillary columns are arranged in series, such that the second column receives only small preselected fractions eluting from the first column. The technique offers complete separation and increased sensitivity. The possibilities of the technique are demonstrated for toxic PCB congeners which were quantitated accurately for the first time in Clophen and Aroclor commercial mixtures and a seal blubber extract. The relative concentrations differed considerably between blubber extract and the commercial mixtures.
