WebCALCULATING Rf VALUES The scientific measure of the chromatographic separation in TLC is the Rf value, variously interpreted in different sources as retardation factor, ratio to the front, etc. (see p. 788). It is given by the expression See fig. 20.8 on p. 788 for an example. Some spots are somewhat large, while others “tail.” WebJan 2, 2024 · To calculate the value of the Rf, you just have to apply this simple formula: Rf (spot) = (distance the spot has moved)/ (distance solvent front moved) A visual example: …
