本文用线性溶剂化能关系（LSER）方法对溴化正丁基咪唑的高效液相色谱固定相进行了表征。根据28种供试溶质与固定相之间的分子间相互作用，系统地评价了固定相的保留特性。与传统反相体系的比较表明，在乙腈/水混合体系中，该体系的保留性能与苯基相相似。用乙腈/水混合物获得的结果也与使用甲醇/水混合物获得的结果进行了比较。
A new HPLC stationary phase based on n-butylimidazolium bromide has been characterized by a linear solvation energy relationship (LSER) approach in the binary acetonitrile/water mobile phases. The retention properties of the stationary phase were systematically evaluated in terms of intermolecular interactions between 28 test solutes and the stationary phase. The results and further comparisons with conventional reversed phase system confirm that retention properties are similar to phenyl phases in acetonitrile/water mixtures. The results obtained with acetonitrile/water mixtures are also compared with results obtained using methanol/water mixtures.
