partition chromatography
Quick Summary
Partition chromatography is a separation technique where components of a mixture are divided between a mobile fluid stream and a stationary phase. The mobile phase can be a liquid or gas, while the stationary phase is a solid or liquid. Solute molecules move between these phases, with different species being transported at different rates based on their affinity for the stationary phase. This differential migration allows for the separation of mixtures. In partition chromatography specifically, the stationary phase is a liquid coated onto a support material, and retention is primarily based on the solute's solubility in this stationary liquid. This method is highly versatile and used across biological and chemical fields for analyzing complex mixtures.12

…technique came to be called partition chromatography. At that time, Martin and Synge suggested that the moving phase could well be a gas. It is a historical oddity that this idea was overlooked for nearly a decade, possibly because of the war, until Martin in collaboration with the British chemist…
