What is the definition of chromatography?

Chromatography is a scientific technique used to separate and analyze different components of a mixture. It is based on the principle of differential migration, where the mixture is dissolved or dispersed in a mobile phase and flows over or through a stationary phase. As the different components have different affinities for the two phases, they move at different rates and become separated. The separated components, often represented as peaks on a chromatogram, can then be identified and quantified. Chromatography finds immense applications in various fields such as chemistry, biology, forensics, and environmental science, contributing to the understanding and advancement of scientific research and analysis.
