Chromatography||Chromatography must be performed between two phase systems. One phase is a stationary phase and requires a support, either solid or liquid. The other phase is the mobile phase, which is a liquid or a gas. When the mobile phase flows through the stationary phase, the separation of the separated material between the two phases, from equilibrium to loss of equilibrium to equilibrium, is the process of adsorption and desorption. As the mobile phase continues to flow forward, there is a difference in the rate of forward movement between the separated materials, and a number of zones are gradually separated from the beginning of the single zone. This process is called the formation. The coefficient K is the concentration ratio of the substance in the two phases. When the valu...
