Ion Exchange HPLC
Ion exchange chromatography is used to retain charged analytes

Ion Exchange HPLC

Ion-exchange (IEX) chromatography involves interactions between a charged stationary phase and the oppositely charged mobile analytes. In cation-exchange chromatography positively charged molecules are attracted to a negatively charged stationary phase. Likewise, in anion-exchange chromatography negatively charged molecules are attracted to a positively charged stationary phase.

Ion-exchange (IEX) chromatography is useful for a wide variety of compounds, such as acidic (anionic) and basic (cationic) small molecules up to peptides and proteins.
