Ion chromatography - Wikipedia

Ion chromatography, (or ion-exchange chromatography) separates ions and polar molecules based on their affinity to the ion exchanger. It works on almost any kind of charged molecule—including large proteins, small nucleotides, and amino acids.However, ,ion chromatography, must be done in conditions that are one unit away from the isoelectric point of a protein.
