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. WebIon-exchange high-performance liquid chromatography (HPLC; on Ultropac TSK DEAE and CM) is compared with conventional soft-gel ion-exchange chromatography in identical peptide purifications. The results show that separating properties are similar, but as expected, ion-exchange HPLC has a much higher resolving capacity and a higher … 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. cryptoworldpro.com
