Stationary phase for liquid chromatography using chemically modified diamond surfaces

摘要

Hydrophilic diamond surfaces comprise surface oxygen bonded onto diamond surface only through oxygen/carbon single bond. The hydrophilic diamond surfaces are treated with strong reductant (e.g., lithium aluminum hydride) to reduce oxygen/carbon double bonds to oxygen/carbon single bond. The hydrophilic diamond surfaces can be used as stationary phase for liquid chromatography.
