“…It can be applied to samples containing commercial PCB formulations (manufactured and sold in the United States by the name Aroclors), metabolized or environmentally altered Aroclors, or non-Aroclor PCBs (such as incidentally generated PCBs). Aroclor mixtures have been characterized with various GC detectors, such as electron capture and flame ionization (3)(4)(5)(6)(7)(8)(9)(10)(11) as well as MS (12)(13)(14)(15). Results have varied with the type of GC column available for separation of Aroclor components and with the approach to detector calibration.…”

“…For example, individual PCBs in an Aroclor are affected differently by exposure to environmental conditions, and the resulting chromatograms or total ion current profiles (TICPs) produced by sample components may not closely resemble the pattern produced by an Aroclor (9,16,17). In addition, the composition of Aroclor mixtures may vary from one batch to the next (9,18). One well-known example of variability among batches is the difference between the Aroclor 1242 available from the USEPA Repository and the specific batch of Aroclor 1242 used by Webb and McCall (4) to develop their technique for Aroclor measurements.…”

PCBs were not specifically identified, this GC/MS approach provided other valuable information, including the relative retention time, relative abundance, and level of chlorination of the congener(s) represented by each GC peak. Acquired data were used to identify and measure Aroclors in two solutions, one containing four Aroclor mixtures and one containing seven Aroclor mixtures. EXPERIMENTAL SECTION Materials.The nine PCB calibration congeners were obtained from Ultra Scientific, Hope, RI, and were used without purification. The internal standard, chrysene-d,,, was obtained from Aldrich Chemical Co., Milwaukee, WI.
