摘要:
Method and apparatus for the detection and quantitation of polychlorinated biphenyls (PCB's) utilizing sample preparation by treatment with predetermined quantities of sulfuric acid and lower alkane, in which the alkane-extracted phase is subjected to chromatographic separation of PCB components (116) and electron capture detection of the separated PCB components (118), and in which the detector response is analyzed by pattern recognition comparison (316) for determination and quantitation of PCB's presented in the sample with stored data for standard PCB mixtures.
