The influence of the type of organic modifiers on retention behavior in micellar liquid chromatography is studied. A group of amino acids and small peptides was used as the test mixture. It is shown that the chromatographic selectivities of 2-propanol, acetonitrile and tetrahydrofuran which belong to three different groups in Snyder's classification, are considerably similar in the presence of micelles for the test mixture. On the other hand, the selectivities of 2-propanol and butanol which belong to the same solvent selectivity group are different for these solutes in the micellar mobile phases.
研究了有机改性剂类型对胶束液相色谱中保留行为的影响。使用一组氨基酸和小肽作为测试混合物。结果表明，在Snyder分类中属于三个不同组的2-丙醇、乙腈和四氢呋喃，在胶束存在下对测试混合物的色谱选择性相当相似。另一方面，在胶束流动相中，属于同一溶剂选择性组的2-丙醇和丁醇对这些溶质的选择性不同。
