Volatile Property of Electronic Cigarette Composition by ATR-FTIR

Electronic cigarette has been said to be a less harmful substitute for traditional tobacco cigarette, customized e-liquid offers various flavors and unique experience smokers. Different from electronic uses heater atomizer heat aerosolize the e-liquid. The study composition its combustion product are flourishing thanks developing analysis instruments methods. However, volatile property, influence of e-cigarette smoke on environment human health still remain unclear. In this study, we choose RELX P53a with watermelon-flavor pod analyse by ATR-FTIR, volatility discuss health. We find that propylene glycol(PG) vegetable glycerin(VG) two main emission, small amount nicotine is added benzoic acid form salt, which have negative effect than pure in cigarette. One follows exponential process rate falls increase RH. flow air then increased test whether these deposited emissions could removed. result shows will stay body atmosphere not easily cleared. Further studies required compositions such as flavor essence seek reasonable regulation formula
