WebJul 18, 2024 · Interpretation of the thin layer chromatography (TLC) is totally based on the Rf values. The Rf values evaluate the relative polarity, the relative affinities with stationary and mobile phases, the relative molecular weights, and even the concentration of analytes if sophisticated environments are used. Why do we need the Rf value?
