Separation of molecules is performed using Size Exclusion Chromatography (SEC), which separates molecules based on size as they pass through a porous resin. Widely used for both preparative and ...

Reviewed by Dr. Catherine Shaffer, Ph.D. Chromatography (from the Greek words chroma, "color," and graphein, "to write") is a method for the separation of a mixture. In simple terms, the process ...

The wide range of chromatographic techniques share one common aim: to separate a material into its components. A material, your sample, is dissolved in a solvent, called the mobile phase. This mixture ...

Explore different protein purification methods like ion exchange, affinity chromatography, and size exclusion, and understand ...

Fast protein liquid chromatography (FPLC) is, as the term implies, an effective (fast) liquid chromatography technique for the separation of protein molecules. The term also implies that the mobile ...

Mindset and economics, not technical feasibility, often block greener solvent adoption; method developers should be ...
