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

Abstract

Optimum conditions for chromatographic separation, at 30 °, 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.
