HS-GC/MS法测定烟用水基胶中挥发性有机物

Determination of volatile compounds in water-based cigarette adhesives by headspace-gas chromatography/mass spectrometry

为了研究烟用水基胶中挥发性有机物的通用检测方法,采用10 m L水作为基质校正剂,静态顶空法进样,GC/MS法分析,内标法定量,建立了测定烟用水基胶中18种挥发性有机物的顶空-气相色谱/质谱(HS-GC/MS)联用法。结果表明:18种挥发性有机物可在26 min内有效分离,且线性关系良好(R^2>0.999),检出限(LOD)为0.004~6.932 mg/kg,加标回收率在80.4%~127.8%之间,相对标准偏差(RSD)≤7.9%。该方法操作简便、绿色环保、适用范围广且通量高,适合水基胶中挥发性有机物的测定。

In order to establish a general method to determine the volatile compounds in water-based cigarette adhesives, a headspace-gas chromatography/mass spectrometry （HS-GC/MS） method for determining 18 volatile compounds in water-based cigarette adhesives was established. The method used 10 mL water as the matrix correction agent, and adopting the static headspace sampling to quantify with an internal standard. The results showed that： 1） The volatile compounds were separated effectively within 26 min. All the volatile compounds had a good linear relationship （R^2〉0.999）. The recoveries of 18 volatile compounds were in the range of 80.4%-127.8% at three spike levels with relative standard deviations no more than 7.9%. The LODs of 18 volatile compounds ranged from 0.004 to 6.932 mg/kg. This method is convenient, environment-friendly, universal and of high throughput, it is suitable for determining the volatile compounds in water-based adhesives.
