The main idea behind chromatography is the separation of a mixture of two or more compounds by using two auxiliary phases one of which is the static phase and the other the mobile phase. The physical state of the static or stationary phase can be solid or liquid whereas the mobile phase can be liquid or gaseous. All chromatographic methods can be classified into four main classes based on the combination of the physical state of the mobile and static phases  

Mobile phase is liquid and static phase is solid. The main principle of the separation by this method is adsorption on the static phase.
