From: Nicotine delivery from the refill liquid to the aerosol via high-power e-cigarette device
Impact of the PG/VG ratio on the un-puffed and aerosolized nicotine concentration (expressed in mg per mL of refill liquid solution). Experiments were performed in triplicate with a power level fixed at 15 W, a dilution ratio of 1.5 and a same volume of aerosol collected into the cascade impactor for all experimental conditions.
