直接进样气相色谱法分析有机芳香酸

Determination of Aromatic Acid by Gas Chromatography in a Direct Injection Mode

用实验室合成的十二烷基苯磺酸甲铵配成固定液溶液,以汞塞动态法制备成毛细管色谱柱.讨论了该毛细管柱的制备方法、对有机芳香酸的分离以及定量分析问题.

In this paper, methyl ammonium dodecanylbenzosulfonate as stationary liquid and the capillary column prepared by the method of dynamic coating with mercury plug are described. The separation and quantitative analysis of aromatic acid were investigated.
