ADSORPTION MEDIUM AND METHOD OF PREPARING SAME

摘要

The present invention encompasses novel coated particles that are well suited for use as absorption media in chromatographic processes. The coated particles comprise a substrate, such as aluminum, silicon, titanium or zirconium oxide particles, containing polymerized silane moieties on a surface of the substrate. The silane moieties include two or three olefinic groups as well as at least on useful ligand. Methods of preparing these coated particles are also described.
