How does adsorption occur in chromatography?

• Adsorption in chromatography occurs when molecules attach to the surface of a solid stationary phase through physical or chemical interactions.
• Different compounds adsorb to the stationary phase with different strengths because their molecular properties influence surface attraction.
• Adsorption strength determines the rate at which compounds detach from the stationary phase and continue moving through the system.
