An improved method is described for separation of peptides and alpha -amino acids using the Chelex X-100 exchanger in the Cu2 + form. After equilibration of the resin with ammonia solution, pH 10.3, acidic and neutral peptides and acidic amino acids are eluted with water. The neutral amino acids and basic peptides are eluted with 1.5 M NH4OH.
