GAS-CHROMATOGRAPHIC SEPARATION OF POLYCHLORINATED-BIPHENYLS ON A NEW APOLAR CAPILLARY COLUMN

Eighty one polychlorinated biphenyls (PCBs) and nineteen chlorinated p esticide standards have been analyzed on a newly developed apolar high resolution gas chromatography (HRGC) column. Emphasis was placed on t he determination of PCB indicator congeners which are part of national regulations, and of toxic coplanar PCB congeners, The new column enab les almost unambiguous quantification of the PCB indicator congeners ( PCB 138 can be separated from both PCB 163 and PCB 164; PCB 28 and PCB 31 were also separated and no coelution was observed for PCB 52, PCB 118, and PCB 180). The new column furnished better results than CP-SII 8 for the analysis of PCB indicator congeners in a sample of seal blu bber.
