| 摘 要： | 制备了新型高效棒状（甲基丙烯酸－苯乙烯－二乙烯基苯）共聚物高效液相色谱柱，扫描电镜显示其具有大孔网络结构，从而表现出良好的通透性。以乙腈－水（９０／１０，Ｖ／Ｖ）为流动相，在流速为２．０ｍＬ／ｍｉｎ下，柱压仅为２．５ＭＰａ，采用等度淋洗实现了多环芳烃及芳香酸的分离。该方法简便且重现性好，具有很好的发展潜力。

| Abstract: | A novel high efficiency rod-shape poly(methacrylic acid-co-styrene-co-divinylbenzene) high performance liquid chromatographic column was prepared by a free-radical polymerization directly within the column. Scanning electron micrograph revealed the macropores of the copolymer column media. It had excellent permeability and the column pressure was only 2.5 MPa at a flow-rate of 2.0 mL/min with acetonitrile-water(90/10, V/V) as mobile phase. It also showed the rather high efficiency with the theoretical plates being 40,000 plates per meter. Aromatic acids and polycyclic aromatic hydrocarbons were separated within 4 and 10 minutes, respectively. |
