Adsorption Characteristics in Reversed-Phase Liquid Chromatography Using Ethanol/Water Mixed Solvent
作者： Kanji Miyabe
关键词:
摘要: Adsorption characteristics were studied in a reversed-phase liquid chromatography consisting of an octadecylsilyl (ODS)-silica gel and ethanol/water mixture (70/30, v/v), compared with corresponding results obtained by using methanol/water acetonitrile/water mixtures v/v) as mobile phase. Similar tendencies observed for some adsorption the three chromatographic systems. However, magnitude was not entirely identical Surface diffusion dominant intraparticle ODS-silica particles irrespective type organic modifiers phases. A few correlations confirmed regard to surface diffusion, i.e., enthalpy-entropy compensation linear free-energy relation. The analogous on phenomena suggest similarity mechanism
