The core principle of paper chromatography is the partition of solutes between the stationary phase (water on paper) and the mobile phase (solvent). While solubility in the mobile phase and interaction with the stationary phase are factors, the overall process is governed by the partition coefficient of each substance between the two phases.
The principle involved in paper chromatography is
