对甲苯磺酸正丁铵毛细管色谱柱的制备及性能考察

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。

Preparation and Characterization of Capillary Gas Chromatographi c Column Using Butylammonium Toluensulfonate as Stationary Phase

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 ∶1　V/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.
