Partition chromatography is a type of chromatography that separates compounds based on their differential partitioning between two immiscible liquid phases. One liquid phase is the stationary phase, typically coated onto a solid support or immobilized as a thin film. The other liquid phase is the mobile phase, which is a liquid solvent that moves through the stationary phase.

The separation process relies on the principle of solubility. Compounds in the mixture will dissolve to varying degrees in both the stationary and mobile phases. Components that are more soluble in the mobile phase will travel faster through the column, while those that are more soluble in the stationary phase will move slower. This difference in migration speed leads to the separation of the mixture into its individual components.

Partition chromatography can be performed in different formats, including column chromatography and planar chromatography (like paper chromatography and thin-layer chromatography). The choice of stationary and mobile phases is crucial for effective separation and depends on the chemical properties of the compounds being analyzed. It is a widely used technique in analytical chemistry for separating and purifying a variety of substances, including pharmaceuticals, biological molecules, and environmental pollutants. The efficiency of separation is influenced by factors such as column length, flow rate of the mobile phase, and the interaction between the analytes and the stationary phase.
