| Abstract: | This paper studies the detection mechanism of the polychlorinated biphenyls（PCBs）.Discussions and analysis are made on the latest technological progress in the fields concerned.Focuses are set on solid phase micro extraction（SPME） and pre-processing stage in the PCBs.The method is proposed to improve the sensitivity of GC-ECD and the solid-phase micro-extraction column adsorption efficiency of PCBs,as well as the speed of implementing the higher efficiency of separating coplanar PCBs with different polarity from GC. |
