How does mobile phase composition affect adsorption in chromatography?

• In adsorption chromatography, the mobile phase influences adsorption by competing with sample molecules for interaction with the stationary phase surface.
• A stronger mobile phase reduces adsorption by displacing compounds from the stationary phase more effectively.
• Changes in mobile phase composition alter adsorption strength and therefore modify the rate at which compounds migrate through the column.
