1. Introduction 

Ion exchange (IEX) chromatography is a very effective method for the separation and purification of biomolecule. The method mainly relies on the interaction between positive and negative charges, and uses the charge properties and number difference of biological molecules under specific conditions to separate them. It has the characteristics of high load, good resolution, easy to control and easy scale-up. It has been widely used in medicine, chemical industry, metallurgy, food and other fields.
