The development of single particle aerosol time-of-flight mass spectrometry and its application in cigarette smoke analysis

摘要

1. The signal strength of nicotine fragment in old particles is larger than that in fresh cigarette particles. The nicotine signal also increase with the particle size. 2. After a 24-hour aging, secondary ion species increase in the old particles, while primary ion species decrease. 3. Classification results show the fine distinctions between different brands of cigarettes.
