Quick Summary

Adsorption chromatography is a technique in analytical chemistry used to separate mixtures. It involves a stationary phase, typically a solid adsorbent like silica or alumina, and a mobile phase, which is a liquid or gas. The separation occurs because different components of the mixture have varying affinities for the stationary phase. Substances that interact more strongly with the stationary phase move more slowly through the column, while those with weaker interactions travel faster. This difference in migration rates allows for the separation of the mixture's components. Adsorption itself is the process where molecules collect on the surface of a solid.123456

Retention mechanism
In adsorption chromatography solute molecules bond directly to the surface of the stationary phase. Stationary phases may contain a variety of adsorption sites differing in the tenacity with which they bind the molecules and in their relative abundance. The net effect determines the adsorbent activity. Partition…
