Read MoreAdsorption and desorption are the main processes operating in chromatography. It is the relative rates of adsorption and desorption onto and off the stationary phase that allows chemicals in samples to be separated. If the column conditions favour adsorption of a molecule then the molecule will adhere to the stationary phase and be separated
