WebApr 7, 2024 · The basic formula for the calculation of Retention Volume in adsorption Elution Chromatography is given as: log R0 (ml/g) = log Va + α (S0 - e0 At) Where Ve and α are the relative parameters of the adsorbent. α is the adsorbent activity. Va is the adsorbent surface Volume (ml/g) S0 is the sample adsorption energy. WebThe R f (retardation factor) value is the ratio of the solute’s distance travelled to the solvent’s distance travelled. The word comes from chromatography when it was discovered that a given component will always travel the same distance in a given solvent under the same conditions. The R f value is a physical constant for organic molecules ...
