Ion exchange (IEX) chromatography is a technique that is commonly used in biomolecule purification. It involves the separation of molecules on the basis of their charge. This technique exploits the ...

Chromatography is the science of separating molecules of interest to identify, quantify or even purify them. Properties of the target molecules such as their solubility, size or hydrophobicity give ...

Chromatography of charged analytes is often challenging as they are not retained effectively on the commonly used reversed phase columns and elute in the dead volume. On columns with polar or aqueous ...

Ion exchange separates components in a sample depending on their relative ionic strengths and interaction with the stationary phase. The stationary phase is a charged substance that selectively ...
