WebIon exchange chromatography involves the separation of ionizable molecules based on their total charge. This technique enables the separation of similar types of molecules that would be difficult to separate by other techniques because the charge carried by the molecule of interest can be readily manipulated by changing buffer pH. WebThese are: Adsorption chromatography. Ion exchange chromatography. Gel filtration chromatography. Affinity chromatography. Gas chromatography, and. High-performance liquid chromatography. Let us now take a brief look at these different types of column chromatography with understandable examples where possible.
