摘　　要：为准确测定卷烟侧流烟气中的甲胺和乙胺,通过对烟气捕集方式的考察和色谱条件的优化,建立了卷烟侧流烟气中甲胺和乙胺的稀盐酸溶液吸收-离子色谱（IC）检测方法,并采用该方法测定了10种不同焦油量、不同类型卷烟侧流烟气甲胺和乙胺的释放量。结果表明：1以0.01 mol/L盐酸为粒相物萃取液和气相物吸收液,采用Ion Pac CS16分离柱,在柱温60Ⅲ及10 mmol/L甲烷基磺酸（MSA）为流动相的条件下进行等度洗脱时,目标物可实现基线分离;2甲胺和乙胺在0.02-2.00μg/m L质量浓度范围内线性关系良好,检出限分别为2.58和3.65μg/L,平均回收率分别为85.1%-102.1%和80.7%-107.3%,相对标准偏差（RSD）均小于3%;310种卷烟样品侧流烟气中甲胺和乙胺释放量差异较明显,分别为15.0-31.7和2.9-9.4μg/支,且主要存在于气相部分。该方法适合于卷烟侧流烟气中甲胺和乙胺的定量分析。In order to accurately determine the yields of methylamine and ethylamine in sidestream cigarette smoke, a dilute hydrochloric acid solution absorption-ion chromatography method was established by investigating the means for smoke capturing and optimizing chromatographic conditions, and the yields of methylamine and ethylamine in sidestream smoke of 10 cigarette samples of different types and tar yields were determined. The results showed that： 1） With 0.01 mol/L hydrochloric acid for particulate phase extraction and gas phase absorption, by adopting Ion Pac CS16 separation column at the column temperature of 60 ℃, and taking 10 mmol/L of methane sulfonic acid （MSA） as mobile phase of gradient elution, the target analytes were effectively separated. 2） This method exhibited good linearity in the range of 0.02-2.00 μg/mL. With the relative standard deviation （RSD） less than 3%, the limits of detection were 2.58 and 3.65 μg/L and the average recoveries were in the range of 85.1%-102.1% and 80.7%-107.3% for methylamine and ethylamine, respectively. 3） The methylamine and ethylamine emission in sidestream smoke of 10 samples differed significantly within the ranges of 15.0-31.7 and 2.9-9.4 μg/cig, respectively, and mainly existed in gas phase. This method is suitable for the quantitative analysis of methylamine and ethylamine in sidestream cigarette smoke.
