固定相研究是ＨＰＬＣ技术发展的重要内容，本工作用扫描电子显微技术对用包夹共聚法和分层迭加聚合法制备的硅基ＨＰＬＣ固定相形貌进行观察，考察了胺类阴离子交换剂合成条件对固定相形貌的影响，以及丙烯酸酯类固定相有机物覆盖的均匀性，为ＨＰＬＣ固定相的合成和表征提供了有效的研究方法。
The study of stationary phase is an important part of the development of HPLC technology. In this work, the morphologies of silica-based HPLC stationary phases prepared by sandwich copolymerization and layered superposition polymerization were observed by scanning electron microscopy. The effects of amine anion exchange The influence of the synthesis conditions on the morphology of the stationary phase and the uniformity of the coverage of the organic phase of the acrylic stationary phase provide an effective method for the synthesis and characterization of the HPLC stationary phase.
