目前毛细管气液色谱柱大都是采用涂渍固定液方法来制备的.这样形成的液膜是不稳定的,在高温下会产生固定液流失或重新排列,致使分离效率下降.交联固定相是采用低聚物在毛细管柱内壁进行在位合成,所形成的高分子聚合物不被溶剂所溶解.由此增加了聚合物的热稳定性和化学稳定性.我们采用了聚甲基硅氧烧和四氯化硅在引发 At present, most capillary gas-liquid chromatography columns are prepared by the method of coating the fixing liquid, the liquid film thus formed is unstable, and the fixing liquid is lost or rearranged at a high temperature, resulting in the decrease of the separation efficiency. The crosslinked stationary phase is The oligomer is used for in-situ synthesis on the inner wall of the capillary column, the formed polymer is not dissolved by the solvent, thereby increasing the thermal stability and the chemical stability of the polymer.We use polymethylsiloxane And silicon tetrachloride in the priming
