| 英文摘要 | the separation mechanisms in capillary electromatography (cec) of bare silica - packed column was investigated under aqueous - organic mobile phases. the separations of five typical solutes, including apolar compound (benzene), polar compounds (formamide and dimethyl formamide) and basic compounds (pyridine and quinoline), showed that reverse phase retention, normal phase retention, ion-exchange and electrophoresis mechanisms were involved. the effect of the concentration of organic modifier, the concentration of buffer and the ph value on separation were investigated. due to the hydrophilicity of bare silica, the silica-packed column exhibits the following merit, i. e., the mobile phase composition can change in rather large range of organic modifier content, buffer concentration and ph value. this means that the bubble problem that are usually met in ods-packed column can be minimized with the silica-packed column. additionally, we presented a novel model of cec, termed as dynamically modified silica column cec. five alkyl substitued benzenes were baseline separated with a mobile phase containing cetyltrimethylammonium bromide. |
