The first uses of chromatography involved separating the colored components of plants in the early 1900's. The pigments in a plant can be separated into yellow, orange and green colors (xanthophylls, carotenes and chlorophylls respectively) through this method. The Greek name for color is chroma, and … teach evening classesWebbAs a result, the green color of the chlorophylls masks or hides the presence of the other pigments. Is it possible to have an Rf value greater than 1? Why or why not? In order to have an Rf value greater than 1 the pigment would have to move further than the solvent.
