Due to the vaporization mechanism of e-cigarettes, the aerosol generated mainly contains the components of the liquid itself: propylene glycol, glycerine, nicotine and flavors. A standardized method for the determination and measurement of nicotine, propylene glycol and glycerol in liquids has been published: ISO 20714:2019 „E-liquid – Determination of nicotine, propylene glycol and glycerol in liquids used in electronic nicotine delivery devices – Gas chromatographic method”.
Nevertheless, a comprehensive characterization of aerosol emissions is essential for consumer protection reasons.
However, appropriate and standardized methods are necessary for the analysis of the aerosol. These standard- ized methods for the measurement of emissions from e-cigarettes are currently being developed.
