Being the chromatography medium which includes the pH stable chromatography medium null silica gel adsorbent which

摘要

Chemistry it regards the improved silica gel adsorbent for the chromatography separation which is decorated three functionalities and two functionalities, or three functionalities or the surface of two functionality organic silane with condensation polymerization. The said chromatography medium although the wide pH range and the pH stability which is improved are shown in comparison with the other silica gel adsorbents, in addition keeps all originate in the silica gel adsorbent affirmative sides. It discloses also the method of forming the said improved silica gel adsorbent with tenpureteitsudo multilayer inorganic/organic gurahuteingu.
