Abstract: 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 superficially 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, chemical stability, 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.

Abstract: Water filtration media having a charged material affixed directly to binder material used in the fabrication of the filter media. A microbiological interception enhancing agent is added to the binder directly. The media having a charged material and a microbiological interception enhancing agent both affixed directly on or in a binder material is then combined with core filter media and prepared as a filtration media. A filter is prepared from the treated filter media.
