Abstract
Abstract A vacuum ultraviolet single-photon ionization mass spectrometer, which has the merits of broad-spectrum soft ionization, low fragment peak, low matrix influence, high sensitivity and short response time, is fit for use in the online analysis of mixed volatile organic compounds. In this review, the theory and structural composition of the single-photon ionization mass spectrometer are described, and the current research progress of sampling systems, ionization sources, and mass spectrometers are summarized. Then, a summary is provided on how online analysis has been applied to the fields of atmospheric composition observation, atmospheric chemistry research, environmental monitoring, food detection, etc. Finally, the direction and trends for future work are proposed.
