Ratio of the distance travelled by the centre of the spot to the distance simultaneously travelled by the mobile phase: RF=ba By definition the RF values are always less than unity. They are usually given to two decimal places. In order to simplify this presentation the hRF values may be used: they correspond to the RF values multiplied by 100. Ideally, RF values are identical to the R values used in
column chromatography
