Chromatography is a versatile separation technique widely used to obtain pure compounds from mixtures. All chromatographic techniques depend on a stationary phase, usually a finely divided solid or coated solid, that a mobile phase, usually a gas or liquid, moves through.

Chromatography is a physical method of separation that distributes components to separate between two phases, one stationary (stationary phase), the other (the mobile phase) moving in a definite direction. The eluate is the mobile phase leaving the column.
