Methode zur Herstellung einer Packung für Flüssigkeitschromatographie sowie das so hergestellte Material.

摘要

Packing materials for use in liquid chromatographs are prepared by reacting silica gel or porous glass having silanol groups on the surface thereof with a chemical modifier to chemically attach the chemical modifier to silanol groups on the silica gel or porous glass, and reacting the chemically modified silica gel or porous glass with an end-capping agent in gas phase at 250-500 DEG C to chemically attach the end-capping agent to the residual silanol groups on the silica gel or porous glass.
