摘要
The present invention provides novel chromatographic materials, e.g., for chromatographic separations, processes for their preparation and separations devices containing the chromatographic materials. The preparation of the inorganic/organic hybrid materials of the invention wherein a surrounding material is condensed on a porous hybrid core material will allow for families of different hybrid packing materials to be prepared from a single core hybrid material. Differences in hydrophobicity, ion-exchange capacity, surface charge or silanol activity of the surrounding material may be used for unique chromatographic separations of small molecules, carbohydrates, antibodies, whole proteins, peptides, and/or DNA.
