A procedure combining tunable vacuum ultraviolet (VUV) single-photon ionization with reflectron time-of-flight mass spectrometer has been developed for analysis of individual components in 90# unblended gasoline. Synchrotron radiation used as the ionization source can provide wide energy range and high resolution. All components can be identified by the molecular weights from photoionization mass spectrometry near threshold ionization and the ionization energies from photoionization efficiency spectra. About ninety components are detected in this study, including paraffins, olefins, and aromatics. Quantitative analysis can be obtained by the integrated ion intensity combining with data of photoionization cross-section. It appears that the tunable VUV photoionization mass spectrometry is a complementary method to previous existing ones for the analysis of individual components in gasoline. It may also be useful in other analytical applications.
