E-liquids have been analyzed utilizing liquid chromatography-mass spectrometry (LC-MS) and fuel chromatography-mass spectrometry (GC-MS). The injections (2 µL) had been within the splitless mode, the column was an Agilent HP5 MS, 0.25 micron film thickness, 30 m length by 0.25 mm ID, and temperature programed from 40°C to 285°C.
