ΔRM (stand) as a reliable value for identification purposes in thin-layer chromatography

Abstract This report experimentally confirmed the possibility of calculating the R M value of a substance on different layers if the following data are known: R M value of the reference substance on the standard layer; Δ R M (stand.subst.) of a substance on the standard layer and Δ R M (stand.layer) for the standard substance. For some carbohydrates, characteristic deviations from calculated R M values appeared on different layers.
