Retardation Factor @ Chemistry Dictionary & Glossary

CHEMISTRY GLOSSARY

retardation factor

faktor zaostajanja

Retardation factor, RF, (in planar chromatography) is a ratio of the distance travelled by the centre of the spot to the distance simultaneously travelled by the mobile phase:

Rf = b / a

The RF value is characteristic for any given compound on the same stationary phase using the same mobile phase for development of the plates. Hence, known RF values can be compared to those of unknown substances to aid in their identifications.
