Reactions of the selected ion flow tube mass spectrometry reagent ions H3O+ and NO+ with a series of volatile aldehydes of biogenic significance
Original language description
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
