摘要
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.
