对甲苯磺酸正丁铵毛细管色谱柱的制备及性能考察

摘　要：用动态涂敷法制备了对甲苯磺酸正丁铵玻璃毛细管柱柱1(固定液浓度为7.5%，柱尺寸为35m×0.35mmi.d.)和柱2(固定液浓度为9.2%,柱尺寸为35m×0.30mmi.d.),所用溶剂是丙酮和甲醇(2∶1V／V)的混合溶剂,并对柱性能进行了考察。结果表明,这种色谱固定相具有较强的极性并对饱和烃、芳香烃、饱和酸、芳香酸、极性异构体等具有良好的分离效果。

Abstract：Capillary gas chromatographic column 1 (7.5% W/W,3 5×0. 35mm i.d.) and column 2 (9.2% W/W,35×0.30mm i.d.) using butylammonium 4-to unesulfonate as stationary phase were prepared by the method of dynamic coating with mercury plug, and the solvent used was mixture of acetone and methanol (2 ∶1V/V). The results showed that the column had good chromatograpic pro perties, especially to strong polar compound, such as carboxylic acids and acoho ls could be separated well.
Keywords：Butylammonium 4-tolunesulfonate,stationary phase, gas chr omatographic column
