Reactions of the selected ion flow tube mass spectrometry reagent ions H3O+ and NO+ with a series of volatile aldehydes of biogenic significance
Popis výsledku v původním jazyce
RATIONALE It has been shown that aldehydes are often present in biogenic media. For their analysis by selected ion flow tube mass spectrometry (SIFT-MS), the rate coefficients and the product ion distributions for the reactions of the analyte ions H3O+ and NO+ with volatile aldehydes in the presence of water vapour are required. METHODS The reactions of H3O+ and NO+ ions have been studied with a series of n-aldehydes ranging from acetaldehyde (designated as C2), through undecanal (C11) under the conditions used for SIFT-MS analyses (1 Torr He, 0.1 Torr air sample, 300 K) and over a range of sample gas absolute humidity from 1% to 7%. For comparison, the C5 pentanal isomer 3-methyl butanal, the unsaturated trans-2-pentenal and trans-2-octenal and the aromatic benzaldehyde were also included in the study. RESULTS The H3O+ reactions led to the formation of protonated molecules MH+ and their hydrates MH +(H2O)0,1,2,3, and (MH+-H 2O). The NO+ reactions resulted in the production of NO+M add
