[0002] Chromatography, also known as chromatography or chromatographic method, is a physical and chemical analysis method. It uses the difference in the interaction forces (distribution, adsorption, ion exchange, etc.) between different solutes (samples) and the stationary phase and the mobile phase. When the two phases move relative to each other, each solute undergoes multiple equilibrium between the two phases, so that the solutes are separated from each other.
