How Does Mobile Phase Composition Affect Adsorbents in Chromatography?

Points on mobile phase composition and adsorbents in chromatography:

• Changes in mobile phase composition influence how readily analytes desorb from the adsorbent surface during chromatography. 
• A stronger mobile phase reduces surface interactions by competing with analytes for adsorption sites. 
• This demonstrates that retention occurs specifically at the adsorbent surface.
