Ion-exchange chromatography (IEC) is a subdivision of liquid-solid chromatography, but its importance is such that it deserves special mention. As the name implies, the process separates ions; the basis of the separation is the varying attraction of different ions in a solution to oppositely ...
WebIon Exchange Chromatography is the most widely used chromatographic mode in biopurification and applied in most downstream processing platforms. The typical scheme in IEX of binding the target, washing the column and eluting the target is called ’bind/elute mode’ and is often applied in intermediate purification steps for example in downstream … Web28 feb. 2024 · Figure 2: Mechanism of separation in IEX. A mix of undissociated, partially dissociated and fully dissociated analytes can be separated by ion exclusion chromatography (IEC), which also uses charged stationary phases (Figure 3).
