Popis: A butyl methacrylate–ethylene dimethacrylate–methacrylic acid (MAA) monolithic column was prepared for capillary electrochromatography. The effect of MAA weight percentage on the EOF mobility and column efficiency was studied. BMA–EDMA–MAA monolith with higher content of MAA provided higher EOF mobility as well as higher efficiency. The effect of mobile-phase composition and buffer pH was also investigated. The monolithic columns exhibited a good repeatability and reproducibility of column preparation with relative standard deviation values below 16% in the studied chromatographic parameters.
