Web16 sep. 2024 · Retention/retardation factor (Rf) can be calculated by the relative migration values of solute (analyte) and the solvent front. Rf = Migration of analyte / Migration of solvent front. The calculation of the Rf value is basically the calculation of relative affinities of a solute with the stationary and mobile phases. WebRf values are important because they determine the outcome of most chromatographic processes, particularly TLC and column chromatography. Rf values give relative attributes of analytes like polarities, molecular weights, and solvent affinities, and even the identification of analytes (solutes) can only be done using the Rf values library.
