✦ Synopsis

A dual-column. gas chromatographic, congener-specific methodology was developed that allows determination of polychlorinated biphenyl (PCB) concentrations in water and sediment samples. The linearity of the detector responses was checked over a range of 1000 at the sub-ppb range of total PCB in the dual-column mode, with less than l o ' * g of each congener impinging on the detector. The chromatographic method was checked to ensure that there was minimal interference by the organochlorines with the PCB analysis and vice versa. PCB standards were analyzed, and they yielded values within 10% of the expected amounts. Extracts from sediments were analyzed, and the organochlorine pesticide (OC) values agreed with values obtained using standard methods. The PCB values obtained from the standard and presented methods agreed within a factor of two. Use of the method provides results that are comparable to current methodology, and it requires less time.
