分析说明
Aroclors are commercial mixtures of PCB congeners. Due to their stability, they ave been used in many different industrial and commercial applications. Because of their toxicity and ability to bioaccumulate, production of these materials ceased in 1977. This application demonstrates the separation of two common Aroclor mixtures, Aroclor 1016 and Aroclor 1260 on the SLB-5ms.
