Paper Chromatography Of Plant Pigments Rf Valuesrf = distance pigment travels (cm) distance solvent travels (cm) the bands derived in paper chromatography contain the pigments found in the plant. The bands can be cut. It is defined as the distance travelled by the compound divided by the distance travelled by the solvent. Rf values for a variety of plant pigments, calculated from a chromatogram using hexane, acetone and trichloromethane (3:1:1) for the mobile phase (reiss, 1994).
