Method 1668: Toxic Polychlorinated Biphenyls by Isotope Dilution High Resolution211 Gas Chromatography/High Resolution Mass Spectrometry

摘要

This method is for determination of the toxic polychlorinated biphenyls (PCBs) in211u001ewater, soil, sediment, sludge, tissue, and other sample matrices by high 211u001eresolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS). The 211u001edetection limits and quantitation levels in this method are usually dependent on 211u001ethe level of interferences rather than instrumental limitations. This method is 211u001eperformance-based. the analyst is permitted to modify the method to overcome 211u001einterferences or lower the cost of measurements, provided that all performance 211u001ecriteria in this method are met.
