Background

E-Cigarette Emissions

E-cigarettes are devices employed to vaporize e-liquids containing nicotine and flavor compounds. Existing and emerging governmental regulations impose testing emissions in tobacco products including e-cigarettes. For example, the Tobacco Products Directive (2014/40/EU) of the European Commission prescribes delivery of nicotine doses at consistent levels and reporting of emissions. Besides nicotine, e-cigarette emission may contain aldehydes such as acrolein and harmful and potentially harmful constituents (HPHCs).

Due to its ultra-high sensitivity, high resolving power, and large dynamic range, the Vocus CI-TOF is at present the only analytical device that can assess consistent delivery of nicotine and maximum emission of HPHC puff-by puff in real-time during e-cigarette vaping by a puffing machine.

Solutions

Real-Time E-Cigarette Emission Analysis Using the Vocus CI-TOF
- Test consistent delivery of nicotine as required by TPD (2014/40/EU)
- Puff-by-puff analysis of e-cigarette emissions including nicotine, PG, VG, carbonyls, and flavor compounds
- Highest sensitivity available with sub-ppt limits of detection
- Highest resolving power for real-time compound separation
- Full spectrum acquisition allows measurements of wide range of compounds simultaneously
Exemplificative measurements of consistent delivery of nicotine over a puff time series for two e-cigarettes using Vocus 2R PTR and a puffing machine. The speed of the Vocus allows single puff measurements of emissions in real-time.
