Abstract
The aim of this study is to compare particle size distribution (PSD) of electronic cigarettes (E-cigarette) aerosol with different alcoholic solvents, including alcohol, n-propanol, n-butanol, ethylene glycol, 1,2-propylene glycol, 1,2-butanediol, glycerol, 1,2,4-butanetriol, polyethylene glycol 200 (PEG200), and polyethylene glycol 400 (PEG400). Eff ects of ratio of the most popular alcoholic solvents, propylene glycol and glycerol, in mixed liquid were also studied. Measurements were conducted by electrical low pressure impactor (ELPI) under same voltage during pu? ng. Results showed that: 1) The particle number concentration of alcohol, n-propanol, n-butanol, ethylene glycol, 1,2-propanediol, 1,2-butanediol showed a single peak curve with the range of 0.02-0.05μm, and the peak value was in the order: alcohol≤ n-propanol <n-butanol, ethylene glycol<1,2-propanediol<1,2-butanediol. 2) Glycerol and 1,2,4-butanetriol presented double peak pattern, in the 0.02-0.05μm and 0.1-1μm, respectively. 3) The PEG200 and PEG400 presented double peak too, in the range of 0.05-0.1μm and 0.1-1μm, respectively. 4) Large particle proportion increased when the number of hydroxy group increased from 1 to 3 in these routine alcohols. 5) Particle size diameters increased while number concentration decreased with higher ratio of glycerol in mixed liquid.关键词
