WebAug 23, 2024 · Each spot has a retention factor (Rf) which is equal to the distance migrated over the total distance covered by the solvent. The R f formula is (1) R f = distance traveled by sample distance traveled by solvent The R f value can be used to identify compounds due to their uniqueness to each compound. http://marz-kreations.com/Chemistry/Chromatography/Dyes/RF-Values.html
Rf values: Definition, Calculation and Explanation - PSIBERG
WebThe Rf value of a spot is calculated using: Rf =\ ( \frac {distance \\ travelled \\ by \\ substance} {distance\ travelled\ by\ solvent }\) Rf values vary from 0 (the substance is not... WebThe Rf value can be easily obtained by calculating the distance between the developing solvent and the distance the compound moved. Rf value = distance moved by the compound ÷ distance moved by the developing solvent For example, in the following conditions, the Rf values are 0.6 and 0.2, respectively. buick century key replacement
