Nicotine, propylene glycol (PG), and glycerol measurements

Levels of nicotine, propylene glycol (PG) and glycerin (G) deposited in PBS-filled wells in the exposure system for the three e-liquid formulations tested. This dataset was generated in an in vitro systems toxicology study where Human organotypic buccal and small lung airway cultures were exposed at the air-liquid interface to cigarette smoke and aerosols of different formulations of electronic cigarettes, namely "Test Mix" (flavours, nicotine, humectants), "Base" (nicotine, humectants) and "Carrier" (humectants).
