雪茄烟主流烟气指标测定及稳定性分析

Index measurement and stability analysis of mainstream cigar smoke

雪茄烟规格多样,烟气分析难度高,实验室经验不足,标准化方法较少。为完善雪茄烟主流烟气的分析方法,选择16个国内外的雪茄烟样品在3个实验室分别进行总粒相物、焦油、烟碱、一氧化碳和水分等常规化学指标的测试分析,并将数据与CORESTA雪茄烟分学组12次共同实验结果和CORESTA推荐方法中的结果进行了比较。结果表明:①雪茄烟直径越大,烟气指标稳定性越差;②在该实验中,国内样品的烟气指标稳定性略好于国外;③雪茄烟样品调节方法需要改进;④与卷烟烟气分析相比,雪茄烟烟气测定结果偏差较大,需进行特定条件的试验数据异常值检验。该方法的测定结果接近或略低于CORESTA的重复性值,低于CORESTA的再现性值,采用该操作方法测定雪茄烟烟气指标可行。

Commercial cigars are a diverse product category. In turn their mainstream smoke analysis has been challenging. There are very limited testing experiences and few standardized methods used for cigar products and their smoke testing. In order to improve the analysis method of mainstream cigar smoke, 16 cigar samples were selected from domestic and foreign markets, and the routine chemical indexes, including TPM, tar, nicotine, CO and H2O, of mainstream smoke of these samples were determined in 3 domestic laboratories. The obtained data were compared with the results of CORESTA recommended methods and those determined in the 1st-12th cigar collaborative studies by CORESTA Cigar Group. The results showed that: 1) The larger the diameters of the test cigars were, the worse the smoke index stability would be. 2) In this study, the smoke index stability of domestic cigar samples was slightly better than those of abroad samples. 3) The pre-test conditioning method for cigars needed to be improved. 4)Compared to the analysis of cigarette mainstream smoke, the test results of cigar smoke differed greatly, and outlier detection should be carried out as a part of the data treatment protocol. The standard deviations of the method used in this study were lower than the reproducibility data and close to or slightly lower than the CORESTA repeatability data, which indicated the detailed operation methods adopted in this study was helpful to reduce test method variability.
