| 摘 要： | 毛细管电色谱(CEC)是毛细管电泳(CE)和微径液相色谱(micro—HPLC)技术的结合，是集CE的电子迁移机制和micro-HPLC的分配分离机理发展起来的一种高效微分离技术．CEC以塞子流型的电渗流代替抛物线流型的压力流，具有CE的高效性，能够分离电中性化合物而具有HPLC的高选择性．

| Abstract: | A novel monolithic stationary phase with long alkyl chain ligands was introduced and evaluated in pressurized capillary electrochromatography(p-CEC) by using a mixture of neutral and charged compounds. The capillary monolithic-column was prepared by in situ copolymerization of ethylene dimethacrylate,alkyl alcohol and 2-acrylamido-2-methyl-1-propanesulfonic acid in a quadruple porogenic solvent consisting of 1,4-butanediol/cyclohexanol/docecanol/water. Effects of experimental parameters in p-CEC,such as pressure and electrical field strength,on the separation were investigated. The baseline separation of the components in the mixture was achieved. The monolithic column can be used as an alternative to the conventional capillary column such as the reversed phase ODS. |
