Abstract

Capillary gas chromatography (GC) combined with on‐column radio frequency plasma atomic emission detection was evaluated for the determination of polychlorinated and polybrominated biphenyls (PCBs and PBBs). Quantitation was possible utilizing a single chlorine or bromine calibration curve based on a randomly selected reference compound, because the signal per ng of halogen ranged within 17 % for 29 congeners. Combined with an internal standard to correct for potential plasma quenching from matrix components, this type of universal quantitation represented a sub‐stantial simplification of current calibration procedures. In combi‐nation with relatively low detection limits (1–5 pg/s of halogen), the present work suggested that GC, coupled with on‐column atomic emission detection is a promising technique for the determination of halogenated micropollutants.
