Linear interdependence of R(M) pair values of substances in salting-out planar chromatography

It has been established that in salting-out planar chromatography there is a linear dependence between the pair of R(M) values of substances obtained on one or two sorbents using the same series of aqueous ammonium sulphate solutions (R(M) pair linearity rule). In addition, the proportionality between the distance of the individual points on the regression straight line and the difference in mol % of the salt in the corresponding solvents has been established (proportionality rule).
