WebThin layer chromatography (TLC) is similar to paper chromatography but instead of paper, the stationary phase is a thin layer of an inert substance (eg silica) supported on a flat, … WebHigh Rf in TLC means it elutes fast and retention time is affinity for stationary phase so greater retention time = slower elution, so what you have above is correct. Correct me if I’m wrong but those are two separate things that sometimes may point to the same thing. Retardation factor is a ratio of the distance traveled by substance vs solvent.
