在气相色谱分析中,某一多组分混合物能否完全分离开,主要取决于色谱柱的效能和选择性,而色谱柱的效能和选择性在很大程度上取决于固定相选择和本身的性能。气液色谱的固定相是由固定液和载体构成,就是说在装柱之前必需经过涂膜(一种使固定液涂布在担体上的技术)才能使用。上海试剂一厂有机担体系列是一类新型合成有机固定相,其本身既 In gas chromatography, the separation of a multicomponent mixture depends largely on the performance and selectivity of the column, and the performance and selectivity of the column depend largely on the choice of stationary phase and on the performance. Gas-liquid chromatography stationary phases are composed of a fixative and a carrier, meaning that the coating must be applied (a technique for applying the fixative to the support) before loading the column. Shanghai Reagent Factory organic support series is a new type of synthetic organic stationary phase, which itself
