Proton-transfer-reaction mass spectrometry - Wikipedia
Proton-transfer-reaction mass spectrometry (PTR-MS) is an analytical chemistry technique that uses gas phase hydronium reagent ions which are produced in an ion source. [1] PTR-MS is used for online monitoring of volatile organic compounds (VOCs) in ambient air and was developed in 1995 by scientists at the Institut für Ionenphysik at the ...
PTR-MS - IONICON
PTR-MS (Proton Transfer Reaction – Mass Spectrometry) is the benchmark method for simultaneous real-time monitoring of volatile (organic) compounds (VOCs) without sample preparation in very low concentrations.
PTR-MS: Moving mass spectrometry into the field.
PTR-MS is a “soft” ionization mass spectrometer. Charge is added to each molecule using water, oxygen, or nitrogen oxide molecules which suppress the fragmentation of the compounds, allowing for a more robust analysis of the mass spectrum.
What is Proton Transfer Reaction Mass Spectrometry (PTR-MS)?
Key Advantages of Proton Transfer Reaction Mass Spectrometry (PTR-MS) · Real-time and simultaneous detection of hundreds of VOCs · Lowest available limits of detection (LODs) for real-time VOC analysis
The Proton Transfer Reaction Mass Spectrometer (PTR-MS) measures gas-phase compounds in ambient air and headspace samples before using chemical ionization to produce positively charged molecules, which are detected with a time-of-flight (TOF) mass spectrometer.
