以甲基丙烯酸(MAA)为功能单体的聚合混合物为原料,采用新型表面改性方法,制备了用于高效液相色谱(HPLC)和毛细管电色谱(CEC)的基于合成聚合物颗粒的尺寸均匀的填充材料。这种“分散方法”提供了有效改性的分离介质。在制备过程中使用的MAA的量和反应时间影响色谱分离的选择性,在HPLC和CEC模式和电渗流。该详细的研究表明,分散方法有效地修饰了大孔分离介质的内表面,并且基于引入的MAA的量,可以观察到用于分离某些溶质的排阻机制。
Uniformly sized packing materials based on synthetic polymer particles for high-performance liquid chromatography (HPLC) and capillary electrochromatography (CEC) have been prepared from polymerization mixtures containing methacrylic acid (MAA) as a functional monomer and by using a novel surface modification method. This “dispersion method” affords effectively modified separation media. Both the amount of MAA utilized in the preparation and reaction time affect the selectivity of chromatographic separation in both the HPLC and the CEC mode and electroosmotic flow. This detailed study revealed that the dispersion method effectively modified internal surface of macroporous separation media and, based on the amount of MAA introduced, exclusion mechanism for the separation of certain solutes could be observed.
