卷烟主流烟气中糖和多元醇在不同粒径气溶胶中的分布研究
Distribution of sugar and polyhydric alcohol in aerosol of diff erent particle size in mainstream cigarette smoke
摘要
Abstract
To investigate the distribution of sugar and polyhydric alcohol in aerosol particles of mainstream cigarette smoke, aerosol particles of mainstream cigarette smoke were divided and collected by electrical low-pressure impactor (ELPI). Mass concentrations of sugar and polyhydric alcohol in aerosol particles were determined by gas chromatography-mass spectrometry (GC-MS). The collected samples were extracted with DMF, modifi ed using BSTFA, and separated by a DB-5MS capillary column and detected under selected ion monitoring (SIM) mode. The targets were quantitatively analyzed using internal standard method. Results showed that: 1) Limits of detection (LODs) ranged from 3.2 μg/L to 29.6 μg/L with standard recovery rate ranged from 82% to 112% at three spiked levels for ten sugars and polyhydric alcohols. 2) The sizes of collected aerosol particles from super slim cigarettes with 17.0 mm in circumference and regular cigarettes with 24.3 mm in circumference were mainly distributed within the medium size range (0.144~0.722 μm), and super slim cigarettes showed a fi ner size distribution compared with regular cigarettes. 3) 10 sugars and polyhydric alcohols were all detected in collected aerosol particles and showed similar size distribution patterns for both super slim cigarettes and regular cigarettes. However, the mass concentrations of 10 sugars and polyhydric alcohols in aerosol particles of diff erent size were diff erent. The mass concentrations of 1,2-Propanediol, ethanediol, fructose, glucose, mannose, D-arabinose, D-galactose and D-xylose appeared to first increase and then decrease with the increase of smoke aerosol particle size, and reached maximum level in medium-sized particles (0.261~0.431 μm). In contrast, the mass concentrations of glycerol and xylitol exhibited contrary distribution pattern, showing a trend of fi rst decreasing and then increasing the increase of smoke aerosol particle size, and decreased to the lowest level in particles of medium size (0.431~0.722 μm).关键词
