Abstract
The applicability of proton transfer reactions involving H3O+ ions to trace gas analysis of methanol, ethanol and acetone in human breath is demonstrated, using a conventional Selected ion flow drift tube (SIFD T). The potential of H3O+ for trace gas analysis lies in the slightly smaller proton affinity of H2O as compared to those of many organic co mpounds, thus allowing for non-dissociative proton transfer to these n eutrals resulting in only one product ion for each neutral trace compo nent to be analysed.
