气相色谱-质谱法测试水质7种Aroclor系列多氯联苯的方法验证

The Method Validation of the Determination of 7 Aroclor in Water by GC-MS

Aroclor系列多氯联苯为多物质混合物,定量困难。本文研究了Aroclor系列多氯联苯的组成特点,提出了选取各Aroclor系列多氯联苯中5~10个特征峰,将选取的特征峰面积加和与浓度制作标准曲线进行定量的方法,可作为标准方法的补充说明。

Aroclors, which are mixture of many polychlorinated biphenyls (PCBs), are difficult to quantify. This paper studies the composition characteristics of Aroclor series polychlorinated biphenyls, and puts forward a method of selecting 5-10 characteristic peaks of each Aroclor series polychlorinated biphenyls, and making standard curves by adding the selected characteristic peak area and concentration, which can be used as a supplementary explanation of standard methods.
