目前气相色谱发展的主要方向之一是改进色谱柱的分离效能及发展新的柱材料,化学键合固定相就是其中的一种。 七十年代初期Hastings和Aue首先报道了聚合物与硅藻土表面的羟基进行化学键合制备化学键合固定相,并成功地用于气相色谱。除了因为它具有高稳定性、有机溶剂 At present, one of the main directions for the development of gas chromatography is to improve the separation efficiency of columns and to develop new column materials. Chemically bonded stationary phases are one of them. In the early seventies, Hastings and Aue first reported the chemical bonding of the polymer with hydroxyl groups on the surface of diatomite to prepare the chemically bonded stationary phase and successfully used it in gas chromatography. Except because of its high stability, organic solvents
