Silica Gel Column Chromatography and Polarity

Silica gel column chromatography separates compounds by polarity using a column packed with silica gel. The silica gel acts as the stationary phase, and the solvent is the mobile phase. As the mixture moves through the column, the compounds separate into distinct bands.

Silica gel column chromatography separates compounds using a column packed with silica gel as the stationary phase.

For silica gel, affinity is strongly linked to polarity because it interacts with compounds by dipole-dipole interactions and hydrogen bonding through the –OH groups that form on its surface.
