Abstract
The gas chromatographic separation of PCB 138, PCB 163, and PCB 164 in Aroclor mixtures can be achieved by application of a CP-Select for PCBs stationary phase. In technical PCB mixtures with a degree of chlorination exceeding 40% (Aroclor 1242, 1254, 1260, and 1262) these three hexa-chlorobiphenyls were present. The highest concentrations of the PCBs under investigation were found in Aroclor 1260. The ratio PCB 163: PCB 138 increased with an increasing degree of chlorination of technical PCB mixtures.
