英文摘要: The new developed soft ionization source which is used in time-of-flight mass spectrometer is introduced. Proton-transfer-reaction (PTR) ionization is a high sensitive method for volatile organic compounds. Vacuum ultraviolet lamp ionization source is attractive for portable analytical instrument because of its smallness and simpleness. Desorption electrospray ionization provides better solutions for real-time, on-line and high sensitive analysis of volatile and semivolatile organic compounds. Furthermore, it can be used in vivo sampling or living tissue surfaces. Atmospheric pressure direct analysis in real time ionization uses electric excited states of atoms or molecules of carrier gas to produce molecular ions for analysis. Applications of these new ionization methods to various problems are also discussed. The progress in hybrid TOF instruments and miniaturizing instruments is reviewed and perspectives for the development of TOF-MS instrument are provided.
