What is the Mobile Phase in Chromatography?

Definition of Mobile Phase in Chromatography:

The mobile phase in chromatography is the liquid or gas that carries the components of a mixture through the stationary phase of the chromatographic system. It represents the moving phase that transports sample components during separation. In chromatography, the mobile phase is defined by its state of matter rather than by its composition or operating conditions. The mobile phase determines the direction of movement of components within the system but is not itself the separating medium. The term mobile phase refers only to this moving carrier phase and does not include its role, selection criteria, or effects on separation outcomes.
