Gas chromatography using a short packed column (45 cm, 0.2 cm i.d., 2% OV‐101 on Gas‐Chrom Q) with mass spectrometric detection in the selected ion monitoring mode has been found satisfactory for the analysis of lower as well as higher polybrominated biphenyls. Acceptable sensitivity (<1 ng) may be achieved for this method by focusing selectively at either the low ( m/z 20‐600) or the high ( m/z 600‐1000) range of the quadrupole filter (low range for mono‐ through hexabromobiphenyl, high range for hexa‐ through decabromobiphenyl). A tuning technique has been developed for low range and high range polybrominated biphenyls using the ion abundances of perfluorotributylamine as a standard. Standard ions for the quantitation of mono‐ through decabromobiphenyls were selected and validated. The technique was applied to the analysis of a variety of environmental samples.
