标准摘要
[中文适用范围]: 本标准规定了采用电子捕获检测器(ECD)的高分辨率毛细管柱气相色谱法测定非卤化绝缘液体中多氯联苯(PCB)浓度的方法。该方法给出了 PCB 总含量,当需要对 PCB 同系物进行详细分析时特别有用。当可以接受不太详细的分析时,可以使用其他方法,例如 IEC 60997。该方法适用于未使用、回收(包括脱氯和化学和/或物理处理)或使用过的受 PCB 污染的绝缘液体。 [外文原描述]: Specifies a method for the determination of polychlorinated biphenyl (PCB) concentration in non-halogenated insulating liquids by high-resolution capillary column gas chromatography using an electron capture detector (ECD). Gives total PCB content; especially useful when a detailed analysis of PCB congeners is necessary.
