Abstract

A Method has been developed for the separation and enrichemen of there non‐ortho, eight mono‐ortho, and di‐ortho substituted polychlorinated biphenyls (PCBs) from Aroclor formulations and environmental samples. The fractionation is accomplished using high performance liquid chromatography (HPLC) with a 2‐(1‐pyrenyl)ethyldimethylsilysily silca column. GC‐MSD with an optimized temperature program was used for quantitation, Hexane, pentane, cyclohexane, iso‐octane, and 2‐propanol were tested as a mobile phase for the isolation of the thirteen target PCBs in a Aroclor 1242, 1254, and 1260 (1:1:1) misture, Pentane at room temperature with a slow rate of 0.7 ml/min is the condition of choice. The average recovery of thirteen target PCBs spiked in the Aroclor mixture is 99.5% with an average relative standard deviation of 4.5%. The average method detection limit is 8pg/μl. Targer PCBs in the reference solis, incinarator ash, and sediment samples were measured.
