Title:
表面から有機基を取り除いた多孔質混成物粒子
Document Type and Number:
Japanese Patent JP4820401
Kind Code:
B2
Abstract:
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.
