| 英文摘要 | a comprehensive two-dimensional liquid chromatographic system (nplc-rplc) was developed using a vacuum-evaporation interface (vei). a normal-phase liquid chromatography (nplc) with a cn microcolumn was used as the first dimension (1(st)-d), and a reversed-phase liquid chromatography (rplc) with a c-18 monolithic column was used as the second dimension (2(nd)-d). a two-position, ten-port valve with two identical storage loops was used as the interface that enabled alternate sampling of the first column eluent onto the second column untill the analysis was finished. in one of the two positions, the eluent from the first column filled one of the loops and was evaporated at 25 degrees c under vacuum conditions, leaving the analytes stick on to the inner wall of the loop. when the valve was switched to the second position, the effluent from the first column flowed through the other loop, while mobile phase of the 2(nd)-d dissolved the analytes in the loop from the previous cycle and injected them onto the second column, allowing on-line solvent exchange of the fractions from the 1(st)-d to the 2(nd)-d. the utility of the comprehensive 2dlc system was demonstrated in the analysis of standard samples and traditional chinese medicine cnidium monnieri (l.) cuss extract. |
