A novel combined ion source based on a vacuum ultraviolet (VUV) lamp with both single
photon ionization (SPI) and chemical ionization (CI) capabilities has been developed for an …

A laser based vacuum ultraviolet (VUV) light source using resonance enhanced four wave
difference mixing in xenon gas was developed for near threshold ionization of organics in …

Impact cratering can destroy life from local to global scales and result in sudden turnovers of
dominant genera and/or species. Here we report that it can also preserve components of the …

ABSTRACTThe growing concern about air quality and the impact exhaust particles can have
on the environment has resulted in the increased use of alternative fuels. A sampling …

Vacuum ultraviolet single-photon ionization time-of-flight mass spectrometry (VUV-SPI-
TOFMS) has been applied to the detection of volatile organic compounds (VOCs), including …
