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 ...

Ion exchange chromatography (IEX) is a versatile and widely used technique for separating biomolecules based on charge. It plays a critical role in protein purification in research and ...

The term liquid chromatography (LC) refers to a class of physicochemical methods which are used to separate and quantify compounds in a sample. LC is made up of a liquid mobile phase, which carries ...

Chromatography is a technique that is used for separation of mixtures. The name combines the Greek word chroma, or “color,” with graphein, “to write.” The technique was invented in 1900 by Mikhail ...
