| 摘 要： | 采用人工唾液捕集卷烟主流烟气,应用搅拌棒吸附萃取法(SBSE)提取其中的化学成分,利用热脱附(TD)-气相色谱-质谱(GC-MS)进行分析。对脱附温度、脱附时间、冷阱温度、萃取时间及NaCl加入量等影响因素进行考察,获得优化的实验条件。在优化条件下,同一样品的6次测定所得44个组分的峰面积的相对标准偏差(RSD)平均值小于10%,说明所建方法重现性较好。应用本方法分析某品牌卷烟烟气成分的结果表明:SBSE-TD-GC-MS联用技术可用于人工唾液捕集吸收的烟气化学成分的快速分析测定。 |

| Abstract: | The chemical components of mainstream smoke were trapped by the artifical salvia.A novel method for the analysis of the trapped chemical components was established using stir bar sorptive extraction(SBSE) followed by a thermal desorption-gas chromatography-mass spectrometry(TD-GC-MS).The major factors including desorption temperature,desorption time,cryofocusing temperature,extraction time and the addition of sodium chloride were studied.Under the optimized conditions,the average relative standard deviation... |
