Retardation Factor Calculator
Posted by Dinesh onThis calculator calculates the retardation factor using bulk density, solids density, porosity values.
In chromatography, the retardation factor is the fraction of an analyte in the mobile phase of a chromatographic system. In planar chromatography in particular, the retardation factor Rf is defined as the ratio of the distance traveled by the center of a spot to the distance traveled by the solvent front.
Retardation Factor Calculation
Formula:
R = 1 + (rb x rs) ÷ q
Where,rb = bulk density = rs(1-q)
rs = solids density
q = porosity
R = retardation factor
