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 ...

How does ion exchange chromatography work? Biomolecules have functional groups that ionize in solution and impart a specific net charge to the molecule. For instance, proteins are made up of amino ...

Ion exchange columns that use charged stationary phases to separate oppositely charged ions are expensive, suitable for a small range of analytes and have limited separation efficiency. Ion pair ...

This course will present an overview of the state of the art in ion-exchange process chromatography: development, scale-up and optimization of preparative chromatographic processes. The attendees will ...

SEVERAL investigators have recently effectively separated metals by means of paper or thin-layer chromatographic systems using liquid ion exchangers ... of reverse phase chromatography whereby ...
