Chromatography (KROH-muh-TAH-gruh-fee)
A laboratory technique used to separate different substances in a mixture. A gas or a liquid is used to pass the mixture through a column, paper, or special plate that contains absorbing materials. The substances in the mixture are separated based on how far they move through the material. The different substances may be visible to the eye or detected by a special machine.
