A polar stationary phase, used primarily to adsorb analytes from non-polar solvents like hydrocarbons, chloro- or fluoro-substituted hydrocarbons or less polar esters and ethers. Analyte retention can occur through hydrogen bonding, dipole-dipole interactions or in aqueous samples through cation-exchange.
