Etymology

Back-formation from chromatographic, borrowed from German chromatographisch (see there for more); by surface analysis, chromato- + -graphy. The technique is so named because it was developed primarily for the separation of the plant pigments, which would separate in bands of different "colors" (chromato-) .
