Chromatography is a technique used to separate different components of a mixture based on their individual properties. It is used to separate components of a mixture which differ in their rates of migration. In other words, the components that move more quickly through the chromatography medium will separate from those that move more slowly. Diffusion refers to the random movement of particles from high to low concentration and is not the basis for chromatography. Migration refers to the movement of particles in response to an electric or magnetic field, but chromatography does not rely on an external field to separate components. Reaction and sedimentation are also not the basis for chromatography.
