Abstract
Bodies formed of porous, divided or colloidal inorganic material containing surface hydroxyl groups which are modified by grafting to the surface an organic group to establish an --O--Si bond, wherein the organic group has an average molecular weight greater than 150 and contains at least one hydrophilic functional group. The bodies of this invention are well suited for use in chromatography.
