WebFeb 25, 2024 · The key thing to remember is that chromatography is a surface effect. As the liquid starts to move past the solid, some of its molecules (energetic things that are constantly moving about) are sucked toward the surface of the solid and stick there temporarily before being pulled back again into the liquid they came from.
