TL;DR: This first paper of this new research programme presents extensive PTR-TOF-MS studies of three major anaesthetics used worldwide, desflurane (CF3CHFOCHF2), sevoflurane ((CF3)2CHOCH2F), and isoflURane and a fourth one, which is used less extensively, enfluranes, but is of interest because it is an isomer of isofLurane.

TL;DR: In this article, a study of the time evolution of the metastable fraction branching ratios of (N 2 ) + n ions was conducted and the properties of the decay channel with the larger energy release was found to have shorter average lifetime than a channel with a smaller energy release.

TL;DR: In this article, the effect of initial internal energy on the extent of surface-induced fragmentation was investigated in a tandem mass spectrometer for CH 3 + and CH 4 + ions prepared in different ion sources.

TL;DR: In this paper, product ion distributions resulting from the primary reactions of H3O+ with nine D-labeled volatile organic compounds and the subsequent sequential reactions with H2O have been determined using a Proton Transfer Reaction Time of Flight Mass Spectrometer (PTR-TOF 8000 (IONICON Analytik GmbH)) at various reduced electric field (E/N) values ranging from 80 up to 150 Td and for two different absolute humidity levels of air sample.

TL;DR: In this paper, a double focussing mass spectrometer Varian MAT CH5 was used to study the impact ionization of He, Ne, Ar, Kr and Xe.
