Abstract

“Sub-ohm” atomizers with reduced resistance can deliver more power than conventional electronic cigarettes.
Typical battery outputs are 100 W or more. These devices are particularly popular among young users, and can
be a significant source of volatile carbonyls in the indoor environment. Emissions from next-generation sub-ohm
vaping products were characterized by determining e-liquid consumption and volatile aldehydes emissions for
several combinations of popular high-power configurations. Tests explored the effect of dilution air flow (air vent
opening), puffing volume, and coil assembly configuration.
