Paper Chromatography Solvent Front. the stationary phase in paper chromatography is the chromatography paper, whereas the mobile phase is the liquid solvent that the paper absorbs. the formula is: The migration rate of each component will depend on the polarities of the paper and liquid, as well as the components’ solubilities in the solvent. when the solvent front reaches the finish line, the paper should be removed immediately from contact with the mobile phase. R f = distance travelled by a substance ÷ distance travelled by the solvent. an r f value of 1 would mean that the substance has moved as far as the solvent front, so it is very strongly. The figure below shows a typical paper chromatogram of the separation of pen inks. For the distance the solvent has travelled, we measure from the start line to the solvent front. We measure the distance a substance has travelled by measuring from the start line to the centre of its spot. in paper chromatography, the sample mixture is applied to a piece of filter paper, the edge of the paper is immersed in a solvent, and the solvent moves up the paper by capillary action. the distance traveled by the solvent front is measured from the original point of application of the spot to the limit of.
