Proton Transfer Reaction Mass Spectrometry for Plant Metabolomics

Trends in Plant Science, 2020
Volatile organic compounds (VOCs) emitted by plants are a valuable source of information on their growth, theirresponse to stress, and the condition of their habitat. The recent trend in the analysis of low-mass molecules ofplant origin is metabolomics, which in the context of volatiles is often referred ...

Proton-Transfer Reaction Mass Spectrometry

Chemical Reviews, 2009
Proton-transfer reaction mass spectrometry (PTR-MS) is a technique developed almost exclusively for the detection of gaseous organic compounds in air. Volatile organic compounds (VOCs) in air have both natural and anthropogenic sources. Natural sources include the emission of organic gases by living objects, both plants and animals.

Membrane introduction proton-transfer reaction mass spectrometry

International Journal of Mass Spectrometry, 2003
Abstract The combination of membrane introduction mass spectrometry (MIMS) and proton-transfer reaction mass spectrometry (PTR-MS) is explored. The PTR-MS is used to measure properties of a well-characterized membrane material, poly-dimethylsiloxane (PDMS).

Proton-Transfer-Reaction Mass Spectrometry: Applications in Atmospheric Sciences

Chemical Reviews, 2017
Proton-transfer-reaction mass spectrometry (PTR-MS) has been widely used to study the emissions, distributions, and chemical evolution of volatile organic compounds (VOCs) in the atmosphere. The applications of PTR-MS have greatly promoted understanding of VOC sources and their roles in air-quality issues.

Proton Transfer Reaction-Mass Spectrometry Applications in Medical Research

Journal of Breath Research, 2009
Gathering information about a subject's physiological and pathophysiological condition from the `smell' of breath is an idea that dates back to antiquity. This intriguing concept of non-invasive diagnosis has been revitalized by `exhaled breath analysis' in recent decades.
