Abstract
A method of separating analytes in a liquid sample includes flowing the liquid sample through a chromatography column configured for use in liquid chromatography. The chromatography column contains a composition that includes a solid support having an exterior surface, a ligand, and a linker. The ligand includes a polyhedral oligomeric silsesquioxane moiety. The linker is covalently bound to both the polyhedral oligomeric silsesquioxane moiety and the exterior surface of the solid support.
