Journal ArticleDOI
On-line monitoring of volatile organic compounds at pptv levels by means of proton-transfer-reaction mass spectrometry (PTR-MS) medical applications, food control and environmental research
TL;DR: In this paper, a proton transfer reaction mass spectrometer (PTR-MS) was developed which allows for on-line measurements of trace components with concentrations as low as a few pptv.
Journal ArticleDOI
Analysis of Compounds in Human Breath after Ingestion of Garlic Using Proton-Transfer-Reaction Mass Spectrometry
TL;DR: In this article, the components allyl methyl sulfide (1), methyl disulfide (2), diallyl sulfide(3), Diallyl trisulfide, dimethyl sulfide, and acetone (9) in the breath of a test person were analyzed over a time period of about 30 h by means of proton-transfer-reaction mass spectrometry.
Journal ArticleDOI
Improved detection limit of the proton‐transfer reaction mass spectrometer: on‐line monitoring of volatile organic compounds at mixing ratios of a few pptv
Journal ArticleDOI
Aroma release and retronasal perception during and after consumption of flavored whey protein gels with different textures. 1. in vivo release analysis.
TL;DR: A clear correlation was found between individual-specific consumption patterns and the respective physicochemical release patterns in vivo and it was found that the temporal resolution of the release profile played an important role in adequate description of therelease processes.
Journal ArticleDOI
Proton transfer reaction mass spectrometry (PTR-MS): propanol in human breath
TL;DR: Proton transfer reaction mass spectrometry (PTR-MS) based on reactions of H 3 O + ions has been used to measure the concentrations of propanol in 46 healthy persons, yielding an average concentration of about 150 ppb as mentioned in this paper.
