What is Chromatography? Understanding the Scientific Foundation

Chromatography stands as one of the most revolutionary separation techniques in modern analytical chemistry.

At its core, this powerful method separates mixtures by exploiting the differential movement of components between two distinct phases: a stationary phase that remains fixed and a mobile phase that continuously moves.

The fundamental principle is elegantly simple yet scientifically profound: different compounds in a mixture interact uniquely with both phases, causing them to migrate at different rates. This differential migration creates spatial separation, allowing scientists to isolate, identify, and quantify individual components from complex mixtures.
