Development of Dipolar Proton Transfer Reaction Mass Spectrometer for Real-time Monitoring of Volatile Organic Compounds in Ambient Air

Analytical methods for the analysis of volatile natural products

“…332,350 Recently, a novel dipolar proton transfer reaction mass spectrometer (DP-PTR-MS) for real-time and on-line monitoring of atmospheric VOCs has been developed. 351 Compared with conventional PTR-MS with one kind of reagent ion, DP-PTR-MS had three kinds of reagent ions, H 3 O + , OH − and (CH 3 ) 2 COH + , which could be switched according to the actual measurement need. DP-PTR-MS improved the qualitative ability and expanded the detection range effectively.…”

“…332,350 Recently, a novel dipolar proton transfer reaction mass spectrometer (DP-PTR-MS) for real-time and on-line monitoring of atmospheric VOCs has been developed. 351 Selected ion ow tube-mass spectrometry (SIFT-MS) is another powerful tool based on chemical ionization, which has been widely used for the rapid and sensitive real-time detection and quantication of volatile organic compounds. [352][353][354][355] The principle of the SIFT-MS technique has been fully described in ref.…”

Development of the portable mass spectrometer and its application in environmental monitoring

“…Recently, Proton transfer reaction (PTR) ion source has attracted people's attention, which will be an important technique to detect trace amounts of VOCs in atmospheric environment [30][31][32]. PTR-MS can detect the absolute concentration of VOCs within several minutes and consequently the real-time monitoring VOCs changes [33].…”
