CHARACTERIZATION AND INFLUENCE OF ELECTRONIC CIGARETTE CONFIGURATION, E-LIQUID PROPERTIES AND USERS’ BEHAVIOUR ON THE QUANTITY OF VAPORIZED E-LIQUID
An experimental predictive model for nicotine delivery
Currently, health authorities are trying to understand the effect of this new nicotine delivery product on its users’ health in order to regulate it. Most of the existing studies about vaping products are related to the composition of e-liquid or vapour: typically type and size of molecules. However, in these publications, we generally observe a lack of information about the conditions of vaporization. Indeed, to the best of our knowledge, there is no characterization of fundamental vaping parameters. We propose a study highlighting the influence of some of them, proving their importance in emission analysis.
The manipulation have been carried out using U-SAV vaping machine configured by default following the parameters defined in the protocol AFNOR and ISO standards (3s-puff duration, 30s-period, 18.3 ml/s maximum flow, 55 ml of air inhaled, 5 series, 20 puff per series). The influences are observed by measuring the mass of e-liquid vaporized.
The clearomiser used is the CUBIS by Joyetech® with a 1Ω-resistor at 15W. The e-liquid was a 50-50 (PG-VG) with 10% of ethanol and 10 mg/ml of nicotine.
