气相色谱中特殊混合固定相的协同效应研究

A Study of Synergistic Effects on Special Mixed Stationary Phases in GC

在气相色谱中，组份在混合固定液上的保留值具有加和性［１～３］．我们在研究一些特殊选择性固定液进行混合固定相保留行为时，发现存在一定的协同效应［４，５］．本文在以全戊基β－环糊精／ＴｌＮＯ３、有机皂土－３４／ＡｇＮＯ３、全戊基β－环糊精／ＡｇＮＯ３为混...

In the separations of ethylbenzene/benzene, o xylene/benzene, styrene/benzene, styrene/toluene and styrene/ethylbenzene on the mixed stationary phases composed of perpentylated β CD and AgNO 3, perpentylated β CD and TlNO 3, Benton 34 and AgNO 3 in GC, the positive synergistic effects or negative synergistic effects were discoveried. This phenomenon was investigated carefully. The effects of separation temperature, and how the stationary phases to be mixed were accomplished.
