Аннотация:An example of the chromatographic analysis of a mixture of benzene homologues in a microemulsion liquid chromatography (MELC) mode with different surfactants shows that the dependence of the retention of the number of methylene groups has a convex character that is fundamentally different from the normal mode of reversed phase (RP) high performance liquid chromatography (HPLC), where the relationship is exponential. The mechanism of sorption of analytes in MELC is proposed. The analysis of a test mixture of alkylbenzenes shows a difference in the behavior of the enthalpy of sorption in MELC and HPLC modes.
