摘要
为了提高卷烟主流烟气中氨(NH3)的测定效率,对现行标准YC/T 377—2010的离子色谱(IC)测定方法进行了改进,并考察了ISO和加拿大深度抽吸(HC)模式下卷烟主流烟气中NH3释放量变化。结果表明:①采用Ion Pac CS16分析柱、等度洗脱、0.60 mL/min流速和50 mmol/L甲烷磺酸(MSA)淋洗液,15 min内即可完成单个卷烟样品中NH3的测定;②NH3的加标回收率为97.53%～99.13%,相对平均标准偏差(RSD)<5%;③HC模式下主流烟气中NH3含量明显高于ISO抽吸模式下的含量。
In order to improve the determination efficiency of ammonia （NH3） in mainstream cigarette smoke, ion chromatography （IC）method described in the current standard（YC/T 377--2010）was improved, meanwhile NH~ deliveries in mainstream cigarette smoke under ISO and Health Canada （HC）smoking regimes were compared. The results showed that： 1 ）with C S 16 column under an isocratic elution with 50 mmol/L of methane sulfonic acid （MSA） as mobile phase at the flow rate of 0.60 mL/min, the determination of NH3 in one single sample could be completed within 15 minutes; 2）the recoveries of NH3 ranged from 97.53% to 99.13% with the relative standard deviation （RSD）lower than 5%; 3）the NH3 delivery in mainstream smoke of cigarette smoked under HC regime was significantly higher than that under ISO regime.
