Amino acids were analyzed using IC YS-50 for cations. YS-50 is packed with polyvinyl alcohol with carboxyl functional group. Amino acids are separated by reversed-phase mode and ionic interaction, as NN-814 column does Alanine and Glycine elute at the same elution time under this condition. See also Amino Acids (2) (NN-814) .
