AbstractThree chiral compounds were successfully separated in a shea time with two enantiomer separation models on packed-capillary electrochromatograpy ( CEC). (i) 75 mu m I.D. capillaries were packed with 5 mu m beta-cyclodextrin (beta-CD) chiral stationary phase (CSP). Effects of voltage, pH and concentration of organic modifier on electroosmotic now (EOF) and chiral separations were investigated systematically. Enantiomers of a neutral compound (benzoin) and a neutral drug (mephenytoin) were separated within a shea time with high efficiency. Efficiency of 32000 theoretical plates per meter and resolution (R-s) of 1.42 were achieved for enantiomers of benzoin using a beta CD packed column with 6.2 cm packed length. Efficiency of 45000 theoretical plates per meter and R-2 of 3.40 were obtained for enantiomers of mephenytoin. Especially, the enantiomer separation of mephenytion was performed in just 3.4 min with R-s of 2.60. (ii) 75 mu m I.D, capillary was packed with octadecylsilica particles (ODS). Chiral separation of a basic drug, propranolol, was studied with chiral agent, via addition of the dimethyl-beta-cyclodextrin (DM beta-CD) directly into the mobile phase on this column. Baseline separation and efficiency of 81000 theoretical plates per meter were achieved for propranolol.
