The possibilities and limitations of analyses of polychlorinated biphenyls (PCBPs) by capillary gas chromatography and capillary gas chromatography-mass spectrometry have been investigated. Metal capillary columns (WCOT) coated with Apiezon L and OV-101 were not suitable for PCB analyses. Good results were obtained in the separation of model mixtures of PCBs and of Aroclor 1242 on a glass capillary column coated with OV-101. Sources of error are indicated that may be encountered in the characterization of PCB components in Aroclor 1242 by standard additions, Kováts' retention indices and mass spectrometry. The direct coupling of a capillary column (WCOT) to a mass spectrometer produced spectra of the main PCB components, many of which could be used in the identification of isomeric PCBs.
研究了毛细管气相色谱法和毛细管气相色谱 - 质谱法分析多氯联苯（PCBP）的可能性和局限性。涂有阿皮松L和OV - 101的金属毛细管柱（WCOT）不适用于多氯联苯分析。在涂有OV - 101的玻璃毛细管柱上，多氯联苯和Aroclor 1242的模型混合物分离取得了良好结果。指出了在通过标准加入法、科瓦茨保留指数和质谱法表征Aroclor 1242中的多氯联苯成分时可能遇到的误差来源。毛细管柱（WCOT）与质谱仪的直接联用产生了主要多氯联苯成分的光谱，其中许多可用于鉴定多氯联苯异构体。
