Monolithic poly(butyl methacrylate-ethylene dimethacrylate-methacrylic acid) column for capillary electrochromatography.
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.
