摘要
Abstract
[Objective] A method for the simultaneous determination of 17 phthalate esters liquids of electronic cigarettes by gas chromatography-mass spectrometry (GC-MS) was developed and evaluated.[Method] The samples were extracted with hexane, and filtered by 0.45 μm of filter membrane after ultrasound extraction.The identification and quantification were performed by GC-MS in selected ion monitoring (SIM) mode.[Result] The calibration curves of phthalate esters showed good linearity in the range of 50-800 ng/mL, and the correlation coefficients (r)>0.99.The limits of detection for phthalate esters in samples ranged from 0.08 to 0.28 mg/kg and the limits of quantification ranged from 0.25 to 0.89 mg/kg.The average spiked recoveries of 3 analytes ranged from 83.16% to 107.99% with the relative standard deviations (RSD) of 0.97%-4.35%.The method has been applied on the determination of phthalate acid esters in 6 liquids of electronic cigarettes samples.[Conclusion] The method is suitable for the determination of 17 phthalate esters simultaneously in liquids from electronic cigarettes with easy operation, high accuracy and precision.关键词
