Recap of Chromatography: Definition and Purpose

Chromatography is a powerful analytical technique used to separate and identify components in a mixture. At its core, chromatography functions based on the principle of differential migration of substances through a stationary phase while being driven by a mobile phase. The term “chromatography” is derived from the Greek words “chroma,” meaning color, and “grapho,” meaning to write. Although it was initially used to separate colored compounds, its applications have extended far beyond simple color separations.
