Abstract:
A new method was proposed for analysis of the organic compounds in cigarette smoke by high resolution Orbitrap mass spectrometry based on polyacrylonitrile-silica (PAN-SiO2) nanofiber membrane extraction and methanol elution.Hydrophobic PAN-SiO2 nanofiber membrane which was used to enrich small molecular organic compounds in cigarette smoke was prepared by the technology of electrospinning.Several parameters including the concentrations of PAN and SiO2 nanopartical,elecrospining voltage,needle aperture and flow rate of spinning solution were optimized.Under the optimal conditions,a PAN-SiO2 nanofiber membrane with good adsorption performance and great physical strength was obtained.A total of 21 compounds including acetone,styrene,acrolein,isoprene,and acrylonitrile were identified by analyzing the cigarette smoke with Orbitrap MS spectrometry in the positive ion mode.Six organic acids including salicylic acid,malic acid and lactic acid were detected in negative ion mode.The limits of detection and quantification for nicotine were 0.071 ng/L and 0.236 ng/L,respectively.
