A mixture of alanine, glutamic acid and arginine was chroatographed on a weekly basic ion-exchange column at pH 6.1. Forecast the order of elution of the amino acids from the ion-exchange column. Presume only ionic interations between the amino acids and the resin. Are the amino acids separated from each other?
