Description

一种聚合物包裹硅胶核-壳型色谱填料的制备和应用
技术领域
本发明涉及一种高效液相色谱填料,尤其涉及一种聚合物包裹硅胶核-壳型色谱填料的制备方法,主要用于核苷碱基、生物碱、糖类以及磺胺类药物的分离。
背景技术
高效液相色谱(HPLC)是20世纪70年代发展起来的一项高效、新颖、快速的分离分析技术,广泛应用于生物、医药、环境等各个领域。色谱填料是色谱的核心部分,所以研制和开发新型的色谱填料一直是色谱领域一个长久不衰的课题,色谱填料的创新归根到底就是材料的创新。
聚合物作为液相色谱填料具有种类性质多样、无特异性吸附、生物兼容性好、酸碱稳定性强等优点。目前聚合物作为液相色谱填料的方式大致有两种,一种是多孔聚合物微球,但是现有的方法制备的聚合物微球孔径分布广,内部结构和床层结构不均匀,导致微球孔道不规则、渗透率低、力学性能差、柱效率低;另一种是聚合物整体柱,但其主要用作毛细管固定相,难以在常规液相色谱中使用,这些因素极大限制了聚合物在液相色谱填料中的应用。
鉴于聚合物在色谱分离中的存在的潜能,为了推动聚合物在液相色谱填料中的应用,势必要采用一定的手段将聚合物包裹到硅胶表面制备成适用于液相色谱的柱填料。
发明内容
本发明的目的在于提供一种聚合物包裹硅胶核-壳型色谱填料的制备的方法;
本发明的另一目的是对上述制备的聚合物包裹硅胶核-壳型色谱填料的对于核苷碱基、生物碱、磺胺类药物、糖类等的液相色分离性能进行研究。
一、聚合物包裹硅胶核-壳型色谱填料的制备

聚合物单体可采用N-异丙基丙烯酰胺(NIPAM)、甲基丙烯酸甲酯(MMA)、和丙烯酰胺(PAM)等。多孔硅胶与聚合物单体的质量比为5:1~7:1。

多孔硅胶与甲醇的质量体积比为2~2.5g/mL;正己烷和苯的体积比为5:1~7:1。
