| 摘 要： | 建立了测定卷烟主流烟气气相物中的甲烷、乙烯和乙炔气体的气相色谱法,用外标法定量,同时考查了捕集条件和仪器的稳定性.所建立的方法简便、快速、准确,并具有良好的线性关系(r甲烷2=0.9993,r乙烯2=0.9998,r乙炔2=0.9994)及较好的准确度与精密度,回收率均>85%,相对标准偏差<3%.将该方法应用于实际样品检测,结果令人满意. |

| Abstract: | The methane,ethylene and acetylene in gas phase in mainstream smoke were determinated by GC.They were analyzed quantitatively by external standard.The parameters of sampling and the stability of instrument were studied.The method was simple,fast and accurate with good linear relation(methane r=0.9993,ethylene r=0.9998,acetylene r=0.9994).And the recovery was more than 85%,RSD was less than 3%,The proposed method has been applied to analyse samples,giving reliable and satisfactory results. |
