The method of using solid phase extraction( SPE) and gas chromatograph-mass spectrometry( GC / MS)was developed for the determination of aroma components in E-liquids. The Li Chrolut EN solid phase extraction cartridge was used with dichloromethane as eluent,and the aroma components were determined by GC / MS. Aroma components were effectively enriched,meanwhile,glycerol and propylene glycol were removed by the developed method. And the developed method showed good repeatability with RSD lower than 10% for ...
