Medical Term:

two-dimensional chromatography

 

Definition: paper chromatography in which a spot, located originally in one corner of a sheet, is developed in one direction along one side of the sheet, after which the sheet is rotated 90° and developed, with another solvent, in the new direction; the resultant spots are thus spread over the entire paper, producing a “map” or “fingerprint.” Also generalized to include chromatography followed by electrophoresis (or vice versa) and column chromatography followed by paper chromatography.
