Alkyl β-D-glucosides and n-alcohols were separated by high-performance liquid chromatography on a porou gel of a trimethylolpropane trimethacrylate homopolymer, using a mixture of water with methanol or acetonitrile as the eluent. The effect of the methanol and acetonitrile concentrations on the separability was examined, and the optimum concentration of each to separate alkyl glucosides and alcohols with alkyl chain lengths of six to twelve was determined. A model for analyzing the elution characteristics of the solutes for various levels of methanol or acetonitrile is proposed, based upon the chemical potential of the solutes and eluent at the interface between the gel and eluent phases. Conventional column chromatographic separation of an alkyl glucoside and an alcohol was also performed by using gel with a larger particle diameter.
