制备了甲基丙烯酸丁酯-二甲基丙烯酸乙烯酯-甲基丙烯酸（MAA）整体柱。考察了甲基丙烯酸（MAA）质量分数对流动性和柱效的影响。MAA含量较高的BMA-EDMA-MAA整体柱具有较高的流动性和效率。还研究了移动的相组成和缓冲液pH值的影响。整体柱具有良好的重复性和重现性，在所研究的色谱参数的相对标准偏差值小于16%。
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.
