| Abstract: | A home-made vacuum ultraviolet single photon ionization time-of-flight mass spectrometer(VUV-SPI-TOFMS) was introduced,including vacuum system,sampling inlet system,vacuum ultraviolet ionization source,reflection time-of-flight mass analyzer and data acquisition system.Single photon ionization with vacuum ultraviolet light is a particularly soft ionization technique.Volatile organic compounds(VOCs) with ionization energy less than the photon energy(10.6 eV),could be ionized into molecular ions.It was nearly... |
