[kroh-muh-tog-ruh-fee] the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates. Deriving from the Greek word for color, chromatos, chromatography entails separating a substance through a medium. The word was originally used describe the separation of plant pigments. Chromatography is used in the fields of biochemistry and analytical chemistry. Today we will be using water (or isopropyl alcohol) to separate the different pigments in a marker.
