Unmodified, high-purity silica provides a strongly polar surface ideal for normal-phase, adsorption chromatography, and HILIC applications. Through controlled interactions such as hydrogen bonding and dipole–dipole forces, bare silica delivers sharp separations for polar compounds, isomers, and structurally related analytes, offering excellent efficiency and fast equilibration.
