Chromatography

Definition

Chromatography is a laboratory technique used to separate and analyze mixtures of substances by their different interactions with a stationary phase and a mobile phase. This method is essential for purifying compounds, analyzing biomolecules, and is widely applied in fields such as biochemistry and forensic science. The technique relies on the principles of partitioning and adsorption, making it a crucial tool for studying cellular metabolism and energy production, as well as for biomolecule immobilization techniques.
