Abstract:  Ketoses, as a result of significantly lower retention, can be separated from aldoses by chromatography on a polyethyleneimine ion exchanger eluted with water. Efficient group separation of nine ketoses and fourteen aldoses is demonstrated. A method for characterization of ketoses on the basis of their specific rotation in aqueous solutions of molybdate is also presented.
