High-performance liquid chromatographic separation of carbohydrates on a stationary phase prepared from polystyrene-based resin and novel amines.
New anion-exchange stationary phases On (n = 1, 2 and 3) with a dimethylamino terminal functional group, where n is the number of oxyethylene units [-(CH2CH2O)n-], were prepared by the reaction of chloromethylated porous styrene-divinylbenzene copolymer beads and amines [(CH3)2N-(CH2CH2O)nCH2CH2-N(CH3)2]. HPLC separations of monosaccharides (sorbitol, fucose, glucosamine, mannose, glucose, galactose, fructose, allose and altrose) and disaccharides (trehalose, lactose, cellobiose and maltose) were performed successfully on these stationary phases. The ether group of the stationary phases On was found to affect the separation of carbohydrates.
