摘要:
三乙醇胺可以被用作固定液来制作气相色谱柱 .由于三乙醇胺分子量较低 ,固定相容易挥发 ,因而该色谱柱允许使用温度很低 .为了提高此类色谱柱的使用温度 ,用溶胶凝胶法制作了三乙醇胺的毛细管气相色谱柱 .甲基三甲氧基硅烷单体水解后逐渐缩聚成凝胶结构 ,此凝胶也可与含羟基的三乙醇胺以及石英毛细管内壁上的硅羟基脱水缩合 ,因此三乙醇胺与毛细管内壁间通过一系列化学键维系着 .测试结果表明 ,用此法制成的色谱柱最高使用温度可以大幅度地提高 .
Abstract:
Triethanol amine can be used as stationary phase to make capillary columns for GC. As the stationary phase, the molecular weight of triehtanol amine is relatively small and the molecules are easy to evaporate at high temperatures, so the highest temperatures at which the column can be used is limited. In order to be used at high temperatures, the triethanol amine capillary column is made by using so-l gel method. The methyltrimethoxysilane is hydrolyzed and this reaction is followed by condensation, with the three- dimentional gel gradually formed. Triethanol amine and the silanols on the inner wall of the capi-l lary also take part in the condensation so that triethanol amine is actually bonded to the inner wall of the column. The testing result has shown that the maximum temperature at which the so-l gel column can be used is over twice as high as before.
