Abstract: A GC-MS(gas chromatography-mass spectrometer) method was developed for the simultaneous detection of five benzenes(BTEX) and 17 phthalates esters(PAEs) in electronic cigarette liquid. The linear range of the analytes was from 0.05~1.00 μg/mL with R2 0.995 0. The LOD and LOQ is 0.001~0.010 μg/mL and 0.003~0.050 μg/mL respectively. The GC-MS method displayed a recovery of 81.64%~110.48%, and the RSD is 0.55%~9.93%. Compared to the reported method, GC-MS method holds the merits of easy pretreatment, low LOD and LOQ, rapid analysis, and low solvent consumption.
