为了研究加拿大卫生部深度抽吸(HCI)模式对超细卷烟主流烟气中焦油、烟碱和一氧化碳(CO)测试结果的影响,9家实验室利用7台转盘型和5台直线型吸烟机在ISO模式和HCI模式下对4种超细卷烟开展了共同实验研究。结果表明:1HCI模式对主流烟气中焦油、烟碱和CO释放量测试值的影响基本一致;2HCI模式下,焦油、烟碱和CO释放量测试值增加幅度随ISO焦油量降低和/或滤嘴通风率的增大而增加;3HCI模式下焦油和烟碱测定结果的重复性限和再现性限、CO测试结果的重复性限及焦油测试结果的相对再现性限均大于ISO模式,表明HCI模式下焦油、烟碱和CO测试结果的精密度比ISO模式差。
In order to study the impact of HCI pattern on tar, nicotine and carbon monoxide (CO) in mainstream flue gas from ultrafine cigarettes, nine laboratories used seven turntables and five linear smoking machines In the ISO mode and HCI mode for four kinds of ultra-fine cigarettes conducted a joint experimental study. The results show that: the 1HCI mode has the same effect on the test values of tar, nicotine and CO release in the mainstream smoke; the increase of the test values of tar, nicotine and CO emission in 2HCI mode decreases with the decrease of the ISO tar and / Mouth ventilation rate increased; repeatability and reproducibility limits of tar and nicotine determination results of 3HCI mode, the repeatability limit of CO test results and the relative reproducibility limit of tar test results were greater than the ISO mode, indicating that HCI The tar, nicotine and CO test results were less accurate than ISO mode in the model.
