Why Must Adsorbents Remain Stationary in Chromatography?

Points on why adsorbents remain stationary in chromatography are:

• Adsorbents remain physically stationary within chromatographic columns or layers during separation. 
• Their fixed position ensures that analyte retention occurs exclusively at the solid surface. 
• This stationary behavior defines the adsorbent’s role as the solid phase responsible for separation.
