E‑Liquid and Aerosol Characterization of Popular Disposable E‑Cigarettes.

ABSTRACT: Disposable electronic cigarettes are one of the most popular forms of nicotine consumption among both adults and adolescents. Yet, e-liquid composition and the inhaled aerosol emissions from these devices are under-characterized. This work investigated 25 disposable e-cigarettes of various flavors from four popular brands (Flum Pebble, Elf Bar, Esco Bars, and Geek Bar) using a combination of gas chromatography, mass spectrometry, and liquid chromatography, accurate mass spectrometry. We quantified (1) e-liquid composition, including concentration and identity of added organic acids, concentration and R/S enantiomeric identity of nicotine, and the flavor and coolant content, and (2) aerosol mass formation and aerosolized carbonyl species formed in the vaping process. Of the 25 devices teste
