Abstract

Technical advances in proton transfer reaction-mass spectrometry (PTR-MS) and new fields of application are discussed. One recent development in PTR-MS is the introduction of time-of-flight (TOF) mass analyzers. Studies have found that the PTR-TOF 8000 achieves a mass resolution up to 8000, allowing most isobaric VOCs to be distinguished easily. A major development in primary ion preparation is the use of switchable reagent ions (SRI), in which the primary ions can be switched from H3O+ to O2+ and NO+ within seconds. Food and flavor scientists benefit from the technique's real-time quantification with very short response times, which allows for nosespace analysis during eating or drinking. Although several military institutions own and deploy PTR-MS instruments for the detection and analysis of illicit substances such as chemical warfare agents, the field is yet to be explored.
