RF value (in chromatography) The distance travelled by a given component divided by the distance travelled by the solvent front. For a given system at a known temperature, it is a characteristic of the. In RF measurement, the Rf value is a ratio and does not have units. It is calculated by dividing the distance traveled by the compound by the distance traveled by the solvent, both. The standard Rf values for plant pigments using varsol as the solvent are essential for identifying pigments via Paper Chromatography. According to the plant physiology manual by Reiss. The polarity of the solvent significantly influences the Rf value in Thin Layer Chromatography (TLC). Increasing the polarity of the mobile phase enhances the solubility of polar.
