HAOHAN香水中的乙醇测定毛细管柱H-WAX60M*0.25MM*0.25UM

浩瀚色谱（山东）应用技术开发有限公司建立顶空气相色谱(HS-GC)内标法快速测定香水中的乙醇含量.香水用N,N-二甲基甲酰胺(DMF)溶解后,用强极性的hh-wax毛细管色谱柱分离,FID检测器进行检测,内标法定量.香水中乙醇的质量浓度在40～80 g/L范围内与其色谱峰面积呈良好的线性关系,相关系数为0.9996,方法定量限为0.01 g/L.测定结果的相对标准偏差为3.1%(n=6),在5～20 g/L添加水平范围内,样品的平均加标回收率为99.4%～101.1%.该方法简单,快速,结果准确可靠,适用于香水中乙醇含量的测定.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a headspace gas chromatography (HS-GC) internal standard method for the rapid determination of ethanol content in perfume. After the perfume was dissolved in N,N-dimethylformamide (DMF) The polar hh-wax capillary column was separated, detected by FID detector, and quantified by internal standard method. The mass concentration of ethanol in perfume was in the range of 40-80 g/L and had a good linear relationship with its chromatographic peak area, and the correlation coefficient was 0.9996, the limit of quantification of the method was 0.01 g/L. The relative standard deviation of the determination results was 3.1% (n=6). In the range of 5-20 g/L addition level, the average recovery rate of the samples was 99.4%-101.1 %. The method is simple, rapid, accurate and reliable, and suitable for the determination of ethanol content in perfume.
