详细研究了多氯联苯全同系物分析方法的色谱净化和高分辨气相色谱/高分辨质谱分析阶段。讨论了各种净化策略，包括对油性样品的DMSO处理，对所有样品的氧化铝柱净化，以及对共面PCB的PGC（多孔石墨化柱）上的HPLC。HRGC/GMS与概述的清理策略结合使用，以确定所有同系物的GC洗脱曲线。概述了HRGC/HRMS、HRGC（ECD）和HRGC/LRMS作为PCBs最终分析技术的优缺点和存在的问题。预计所提供的数据将有助于分析化学家进行分析，无论是总或planar多氯联苯。在多氯联苯的分析可能的进一步发展进行了讨论。
The chromatographic clean-up and HRGC/HRMS stages of an all congener specific analytical method for PCBs were investigated in detail. Various clean-up strategies, including DMSO treatment for oily samples, alumina column clean-up for all samples, and HPLC on PGC (Porous Graphitized Column) for coplanar PCBs, were discussed. HRGC/HRMS was used in conjunction with the clean-up strategies outlined to determine the GC elution profile of all congeners. The relative merits and problems of HRGC/HRMS , HRGC (ECD), and HRGC/LRMS as the final analytical technique for the determination of PCBs were outlined. It is expected that the data presented will be useful to analytical chemists performing analyses for either total or complanar PCBs. Possible further developments in the analysis of PCBs are discussed.
