液相在高聚物气液固色谱柱中的作用及其对柱分离性能的影响

Role of the Liquid Phase in Gas-Liquid-Solid Polymer Column and Its Influence on Performance

以乙基乙烯苯为单体,二乙烯苯为交联剂,加入不同极性和量的液相,原位聚合制备出了高聚物气液固PLOT柱.研究了气液固毛细管柱形成的过程及其所需的液相量.同时对液相在往分离中的作用进行了考察.

Gas-liquid-solid (GLS) polymer PLOT columns were prepared by in situ copoly-merization of ethylvinylbenzene and divinylbenzene with different polarities and amounts of liquid phase. The role of the liquid phase in these GLS columns and its influence on the performance of these GLS columns were studied by measuring the changes of isosteric heats of adsorption. The required amounts of liquid phase and the forming process of a GLS column can be estimated.
