The stationary phase of this chromatography technique is a liquid supported on an inert solid. Mobile phase is either a liquid (liquid-liquid chromatography) or gas (gas-liquid chromatography). This is based on the compounds’ solubility. In other words difference in solubility is also due the differences in polarity. More polar substances are having higher affinity to the stationary phase. Less polar substances will go into the mobile phase.Paper chromatography comes under this type.
