Abstract

Stationary phases based on titania are obtained by the adsorptive attachment of polyethyleneimine followed by crosslinking with 1,4-butanediol diglycidyl ether. The chromatographic properties of the adsorbents are studied using the Tanaka test for hydrophilic stationary phases and on an example of a separation of a model mixture of water-soluble B vitamins. It is shown that varying the amount of reagents at the stage of synthesis of the stationary phase affects the structure of the functional layer and thereby makes it possible to obtain a adsorbent with improved chromatographic characteristics.

用于亲水相互作用液相色谱的二氧化钛基吸附剂

摘要

基于二氧化钛的固定相通过聚乙烯亚胺的吸附连接然后与 1,4-丁二醇二缩水甘油醚交联获得。吸附剂的色谱特性是使用 Tanaka 测试对亲水性固定相和水溶性 B 族维生素模型混合物的分离进行研究的。结果表明，在固定相合成阶段改变试剂的量会影响功能层的结构，从而可以获得具有改进色谱特性的吸附剂。
