Analysis of Organic Solvent Residues in Acetate Fiber Filter Rod by Headspace Gas Chromatography-Mass Spectrometry

利用顶空-气质联用仪(HS/GC-MS)建立了一种同时测定醋酸纤维滤棒中溶剂残留的测定方法.利用顶空气相色谱技术,用选择离子模式对醋酸纤维滤棒中溶剂残留进行了定量分析.分析结果表明,方法线性关系良好,相关系数均大于0.998 0,检出限为0.010 4~0.157 8 mg/kg.9种溶剂残留的平均回收率为90.3%~102.2%,相对平均偏差小于10%.方法适用于醋酸纤维滤棒溶剂残留的测定且高效、准确、简便.

A headspace gas chromatography-mass spectrometric（ HS/GC-MS） method was developed for the determination of organic solvent residues in acetate fiber filter rod. The target compounds were separated using the headspace gas chromatography and detected by the mass spectrometry in the selected ion monitoring mode. The results showed that the calibration curves were linear and correlation coefficients were higher than 0. 998 0,the limits of detection ranged from 0.010 4 to 0.157 8 mg/kg,the average recoveries ranged from 90.3% to 102.2% of 9 organic solvent residues with relative deviations lower than 10%. The method is efficient,rapid,simple and is suitable for the determination of organic solvent residues in acetate fiber filter rod.
