The fundamental parameter used to characterize the position of a sample zone in a thin-layer chromatogram is the retardation factor, or RF value. It represents the ratio of the distance migrated by the sample compared to the distance traveled by the solvent front, and for linear development is given by R F … Retardation Factor R = 1 + r b k d / q. R = retardation factor. r b = bulk density = r s (1- q) r s = solids density. q = porosity. k d = (soil) distribution coefficient = f oc K oc.

Retardation in general context means negative acceleration (deceleration). It (a) is expressed as delta v over delta t. a= the change in velocity divided by the change in time. 2005-07-19 Formula: a = (v - u 2)÷2s.

Retardation Factor R = 1 + r b k d / q. R = retardation factor. r b = bulk density = r s (1- q) r s = solids density.

Therefore in Rf= Ds/Df,where RF is the retardation factor, Ds is the migration distance of the substance and Df is the migration distance of the solvent front. Retardation factor values are helpful in the identification in comparing unknown and known compounds.

TQ s = Total quantity of substance in the system. R = Retardation factor The first step is to refine the retardation factor mathematically. It is the ratio of the time that a substance spends in the stationary phase to the time that it spends in the mobile phase. Therefore in Rf= Ds/Df ,where RF is the retardation factor, Ds is the migration distance of the substance and Df is the migration distance of the solvent front. Formula: a = (v - u 2 )÷2s.

It shows how many times the migration of the substance subjected to adsorption slower than the actual speed of water flow in pores (Deutch, 1997).
