WebDec 1, 2024 · How do you find the Rf value in chromatography? In thin-layer chromatography, the retention factor (Rf) is used to compare and help identify compounds. 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). ... WebThere are two phases of chemicals in chromatography, the stationary phase and the mobile phase. The stationary phase is the substance that is used in the "background" so as to carry the mobile phase molecules. The products in which one is trying to observe will travel in the mobile phase through the stationary phase.
