Název v původním jazyce

Analysis of the isobaric compounds propanol, acetic acid and methyl formate in humid air and breath by selected ion flow tube mass spectrometry, SIFT-MS

Popis výsledku v původním jazyce

Numerous analyses of exhaled breath using selected ion flow tube mass spectrometry, SIFT-MS, over the last few years have revealed the presence of volatile compounds with molecular weight 60 and the concern has been to identify which of the isobaric compounds from the set of 1-propanol, 2-propanol, acetic acid andmethyl formate are present in human breath. The problem is compounded by the formation of hydrates of the characteristic primary product ions of the reactions of the H3O+ and NO+ precursor ionswith these compounds, this being particularly efficient for humid samples such as exhaled breath. Thus, the resulting product ion spectra are complex and choices have to be made as to which of the characteristic product ions and their hydrates can bestbe used for the quantitative analyses.
