摘要: 双羟基硅胶键合固定相由于具有结构稳定、耐高压和抗溶剂性能强等特点,已引起色谱分析工作者的广泛注意,Regnier等曾合成含有6个碳原子的双羟基极性键合固定相,但由于碳链太短,限制了它在极性有机化合物上的应用。

Abstract: A new silica gel bonded phase, dihydroxy triethylene glycol bonded stationary phase (DHG-BSP), was synthesized. The conditions for preparation, together with its physicochemical properties and applications were studied. It is shown that the DHGBSP is an excellent material with high concentration of bonded phase(394μmol/g), good thermal and chemical stabilities and highly selective separation for aromatic amines and some amino acids.
