How can multiple components separate simultaneously in TLC?

Points on how multiple components separate simultaneously in TLC:

• TLC is carried out on a flat adsorbent surface that allows multiple components of a mixture to separate simultaneously as a solvent spreads across the layer.
• All components begin separation from the same surface and experience solvent movement at the same time.
• This shared exposure enables different substances in the mixture to separate together along the plate surface.
