WebJun 6, 2024 · How is Rf value calculated? The Rf value of a compound is equal to the distance traveled by the compound divided by the distance traveled by the solvent front (both measured from the origin). What is Rf value of chromatography? The Rf (retardation factor) value is the ratio of the solute's distance travelled to the solvent's distance travelled. http://marz-kreations.com/Chemistry/Chromatography/Dyes/RF-Values.html
