摘要：

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.
