摘　　要：采用气相色谱仪建立了一种快速测定2,3-二甲基苯甲硫醚含量的方法,即采用氢火焰离子检测器(FID)、Agilent J&W HP-5毛细管柱,以甲苯作内标。结果表明,此试验条件下,2,3-二甲基苯甲硫醚的浓度与2,3-二甲基苯甲硫醚和内标甲苯相应响应值比之间存在良好的线性关系,其线性相关系数(R2)为0.9996,标准偏差为0.1082,变异系数为0.1224%,平均回收率为100.3%。此方法检测快速、定量准确、操作性强,适用于2,3-二甲基苯甲硫醚的定性和定量检测。A method for rapid determination of 2,3-dimethylthioanisole was established by gas chromatography,using a hydrogen flame ionization detector(FID),an Agilent J&W HP-5 capillary column,and toluene as the internal standard.The results showed that under this experimental condition,there was a good linear relationship between the concentration of 2,3-dimethylthioanisole and the corresponding response value ratio of 2,3-dimethylthioanisole and internal standard toluene,with a linear correlation coefficient(R2)of 0.9996,a standard deviation of 0.1082,a coefficient of variation of 0.1224%,and an average recovery of 100.3%.This method is fast,accurate in quantitative determination,and easy to operate,and is suitable for the qualitative and quantitative detection of 2,3-dimethylthioanisole.
