ABSTRACT:
A material for chromatographic separations, processes for its preparation, and separation devices containing the chromatographic material. In particular, porous inorganic/organic hybrid materials are provided with a decreased concentration of surface organic groups. These particles may be surface modified and have enhanced stability at low pH.
