They therefore have differential affinity for both the mobile and stationary phases of the chromatographic systems. This chromatographic separation is the resultant of propelling (mobile phase) and retarding forces (stationary phase). The stationary phase in strict sense includes the medium (paper) together with the polar solvent (water). The mobile phase or propelling force includes both polar and non-polar solvent. The separation is brought about by continuous partition between the mobile phase (solvent flowing along the paper) and the water held in the paper and paper per se. Paper together with water acts as an adsorbent; it has a strong affinity for polar molecules which are held by hydrogen bonding and vander Waals' forces (Smith & Seakins, 1976).Not Availabl
