基于TDLAS技术测量卷烟燃吸逐口耗氧量
Determination of puff-by-puff oxygen consumption during smoking based on TDLAS technology
摘要
Abstract
In order to detect the oxygen consumption during cigarette smoking, a detection system was developed by incorporating tunable diode laser absorption spectroscopy (TDLAS) technology coupled with a modified single port smoking machine. The results showed that within the oxygen concentration range of 2%-30%, the peak value of its secondary harmonic signal intensity presented good linearity (R2=0.999 1). The system showed higher detection precision (<3%) and less affected by temperature, the puff-by-puff detection sensitivity was of 0.004 a.u/(0.058%); intra-day RSD (0.145%) and inter-day RSD (0.26%) were smaller. The puff-by-puff oxygen consumption of reference cigarette (3R4F) was determined, the results indicated that the oxygen consumption during smoking positively correlated to puff number. The developed detection system features simple structure, short detection time and high time resolution, and has good application prospects for researching cigarette's combustion state and its relationships with cigarette smoke.关键词
