two-dimensional chromatography


Also found in: Encyclopedia.

two-di·men·sion·al chro·ma·tog·ra·phy

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.
