【摘要】 <正> 气相色谱中固定相的选择是决定色谱分离效果的关键性问题,迄今尚缺乏完整的理论指导。9-取代基咔唑化合物具有优良的光电导性能,近来已引起人们广泛的注意,但有关这类化合物的气相色谱分析研究尚未见有文献报导,因此在固定相的选择上缺乏借鉴。本文在分离咔唑系列化合物过程中,按照它们的色谱行为,探讨了这些分子的特性,并据此顺利地选出了能达到预期分离效果的色谱柱。更多还原

【Abstract】 It is a key problem to achieve a satisfactory chromatographic separation of certain group of compounds without so many trials in choice of a proper stationary phase. While separating 9-substituted carbazoles by gas chromatography on stationary phases with different polarities, we carefully studied their chromatographic behaviours and found the difference of molecular interaction between stationary phase and solutes. That leads its to choose a proper stationary phase for a better separation.更多还原
