Early partition chromatography was the liquid-liquid type; now the bonded-phase method has become predominate because of certain disadvantages of liquid-liquid systems. • One of these disadvantages is the loss of stationary phase by dissolution in the mobile phase, which requires periodic recoating of the support particles.
