ION EXCHANGE CHROMATOGRAPHY

open access: yes, 2023
Ion exchange chromatography is a chromatography process that separates ions and polar molecules based on their affinity to the ion exchanger. Ion exchange chromatography is probably the most powerful and classic type of liquid chromatography. It can also used for almost all kinds of charged molecule including large proteins, small nucleotides and amino
