Effects of Counter-ion Form of a Cation-exchange Resin and Ethanol Content of Eluent on the Distribution Coefficients of Galactose, Tagatose, and Talose onto the Resin

摘要

Optimum conditions for chromatographic separation, at 30 degrees C, of galactose, tagatose, and talose were determined by investigation of the effects of the counter-ion form of cation-exchange resin and the ethanol content of eluent on the distribution coefficients of the monosaccharides onto the resin. Resin in the K+ form with a divinylbenzene content of 8% was found to be most suitable for the separation. The distribution coefficients of all the solutes on the resin were increased as the ethanol content of eluent increased.
