摘 要：
为了鉴别黄斑烟中香精斑烟和料斑烟支污染物的来源,利用高场不对称离子迁移谱(FAIMS)法不同离子在强场(>15000 V/cm)条件下离子迁移率呈非线性变化的原理,使黄斑烟支上疑似香精污染物的离子团相互分离,得到待测物质的特征三维扫描图谱。通过图像相似度计算查找软件(Visual Similarity Duplicate Image Finder),对比香精斑烟支污染物和对照样品三维扫描图谱的相似度,鉴别香精斑烟支污染物来源。料斑烟在经过样品处理后,可利用同样的方法鉴别。结果表明:人工分拣香精斑烟支污染物的FAIMS图谱和人造香精斑的FAIMS图谱相似度达到95%以上,人工分拣的烟丝湿团的FAIMS图谱和各类人造污染物的FAIMS图谱相似度约为95%,说明可利用FAIMS分析与鉴别香精斑烟和料斑烟表面污染物来源,且人工观察分拣黄斑烟支归类的方法基本准确。

摘 要：
Characteristics of volatile substances were detected by FAIMS and the mobility of different ions changed nonlinearly under high electric field intensity(> 15000 V/cm), which separated ionic groups of suspect flavor contaminants in staining in cigarette from each other. Characteristic three-dimensional scanning map of the substance was obtained. Image similarity calculation software, i.e. Visual Similarity Duplicate Image Finder, showed similarities of three-dimensional scan map, which would identify causes of flavor stains on surface of cigarette. The same method could be used to identify sugar stains in cigarettes after processing. Results showed that: 1)The similarities of test maps of artificially sorted flavor stains cigarette and man-made pollutants stains were more than 95%. 2)The similarities of test maps of artificially sorted sugar stains cigarette and man-made pollutants stains were about 95%. It was demonstrated that FAIMS could be used to identify pollutant causes of staining in cigarette.
