chromatography   (krō'mə-tŏg'rə-fē)  Pronunciation Key  A technique used to separate the components of a chemical mixture by moving the mixture along a stationary material, such as gelatin. Different components of the mixture are caught by the material at different rates and form isolated bands that can then be analyzed.
