| 英文摘要 | a cellulose trisphenylcarbamate-bonded chiral stationary phase was applied to nano-liquid chromatography (nano-lc) and capillary electrochromatography (cec) with nonaqueous and aqueous solutions as the mobile phases. several chiral compounds were successfully resolved on the prepared phase by nano-lc. the applicability of nonaqueous cec on a cellulose derivative stationary phase was investigated with the organic solvents methanol, hexane, 2-propanol, and tetrahydrofuran (thf) containing acetic acid, as well as triethylamine as the mobile phases. enantiomers of warfarin and praziquantel were baseline-resolved with plate numbers of 82 300 and 38 800 plates/m, respectively, for the first eluting enantiomer. the influence of applied voltage, concentration of nonpolar solvent, apparent ph, and buffer concentration in the mobile phase on the electroosmotic flow (eof) and the mobility of the enantiomers was evaluated. enantioseparations of traps-stilbene oxide and praziquantel were also achieved in aqueous cec with plate numbers of 111 100 and 107 400 plates/m, respectively, for the first eluting enantiomer. a comparison between nonaqueous cec and aqueous cec based on a cellulose trisphenylcarbamate stationary phase was discussed. pressure-assisted cec was examined for the chiral separation of praziquantel and faster analysis with high enantioselectivity was acquired with the proper pressurization of the inlet vial. |
