【摘要】 采用新颖聚合工艺制备用于反相高效液相色谱柱填料的乙基苯乙烯-二乙烯苯球形共聚物,不需使用备有高速搅拌的混匀器和特殊的筛析设备,聚合物粒径的95％在3～7μm之间,测算了渗透性、柱效和峰不对称性等柱参数,并通过分离实例说明该填料对胺类、酚类和芳烃类具有优良分离性能。更多还原

【Abstract】 The spherical copolymer of ethylstyrene with divinylbenzene for using as the packing material for Reversed-phase-HPLC has been prepared by a novel polymerization process. The 95% particle sizes of the polymers are within 3-7 μm. Some column parameters such as the permeability, efficiency and peak asymmetry were calculated. The excellent characters of this packing material for the separation of mixtures of amines, phenols and aromatic hydrocarbons were well demonstrated through several examples.更多还原
