摘要
建立了一种毛细管电泳分析分离邻苯二甲酸和对邻苯二甲酸异构体的方法。胶束电动毛细管色谱(MECC)在110 mM pH 8.3硼酸盐缓冲液中获得最佳分离效果，缓冲液中含有40 mM十二烷基硫酸钠(SDS)和20%甲醇。考察了甲醇、乙腈和-环糊精的加入对异构体分离的影响。所开发的缓冲系统提供了一种可靠的分析方法，可以可靠地确定每种分析物的浓度。
Micellar electrokinetic capillary chromatography analysis of phthalic acid isomers.
A capillary electrophoretic method for the analysis and separation of ortho- and para-phthalic acid isomers was developed. The best separation was achieved using micellar electrokinetic capillary chromatography (MECC) performed in a 110 mM borate buffer pH 8.3 also containing 40 mM sodium dodecyl sulfate (SDS) and 20% methanol. The effect of the addition of methanol, acetonitrile, and beta-cyclodextrin on the separation of the isomers was investigated. The buffer system developed was shown to provide a dependable method of analysis from which the concentration of each analyte could be reliably determined.
