用正相高效液相色谱与气相色谱相结合分离多氯联苯和有机氯农药的方法研究

Separation of Polychlorinated Biphenyls and Chlorinated Pesticides by Normal Phase High Performance Liquid Chromatography(HPLC)-Gas Chromatography(GC)

以电子捕获毛细管气相色谱为测定手段，探讨了用正相高效波相色谱分离多氯联苯和有机氯农药的可能性，并将该方法应用于海洋沉积物样品中有机氯农药的测定。

ombination of normal phase HPLC and GC has been applied to separate polychlorinated biphenyls(PCBs)and chlorinated pesticides. The column used possessed enough ability to separate most of the com-pouiids interfering seriously with GC-ECD. Better results can be achieved in the analysis of chlorinated pesti-cides in sediment samples. It can also be used for many other environmental samples.
