发明名称 |
Porous hybrid particles with organic groups removed from surface |
摘要 |
The invention provides a material for chromatographic separations, processes for its preparation, and separation device 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 resulting in higher bonded phase surface concentration and have enhanced stability at low pH. |
