%X A monolithic capillary column was obtained by in situ co polymerization of butyl methacrylate with ethylene dimethacrylate. A mode of capillary electrochromatography (CEC) based on the dynamic adsorption of long chain sodium dodecyl sulfate(SDS)on the monolithic stationary phases was developed. Effects of SDS concentration and concentration of acetonitrile in mobile phase on the electroosmotic flow(EOF) of the column and the plate height on the electroosmotic velocity were investigated. Efficiency of monolithic capillary column with higher than 140?000 plates per meter for neutral aromatic compounds were obtained, and the relative standard deviations observed for dead time( t 0) and retention times of neutral solutes were about 0.22% and less than 0.56% for ten consecutive runs, respectively .
