Synthesis of the multilayered stationary phases containing quaternary ammonium functional groups on the silica support was described. Bonded phases were characterized by elemental analysis, solid state (13)C NMR spectroscopy and chromatographic methods. The surface of silica support was coated with different number of polymeric layers formed by condensation polymerization of primary amine (methylamine) with diepoxide (1,4-butanedioldiglycidyl ether). A series of stationary phases with different number of polymerized layers were tested. Separation of an inorganic anions sample (F(-), Cl(-), NO2(-), Br(-), NO3(-)) and nucleotides was performed.
描述了在硅胶载体上合成含有季铵官能团的多层固定相。通过元素分析、固态（13）C核磁共振光谱和色谱方法对键合相进行了表征。硅胶载体表面涂覆有不同数量的由伯胺（甲胺）与二环氧化物（1,4-丁二醇二缩水甘油醚）缩聚形成的聚合物层。测试了一系列具有不同聚合层数的固定相。对无机阴离子样品（F(-)、Cl(-)、NO2(-)、Br(-)、NO3(-)）和核苷酸进行了分离。
