WebCalculation. The Retention factor is found using the following calculation: Rf = distance travelled by substance ÷ distance travelled by solvent. The Rf value will always lie between 0 and 1; the closer it is to 1, the more soluble is that component in the solvent. The Rf value is a ratio and therefore has no units.
