Proton Transfer Reaction - Mass Spectrometry
PTR-MS (Proton Transfer Reaction – Mass Spectrometry) technology enables real-time measurement of volatile organic compounds (VOCs). Originally developed by scientists at the Institut für Ionenphysik at the University of Innsbruck, Austria this technology has been commercialized by IONICON Analytik.
Selective Reagent Ionization - Mass Spectrometry
SRI-MS is a new technology where the user can select from different reagent ions for chemical ionization direct injection mass spectrometry, only available from IONICON. Our expertise as the world's leading PTR-MS company lead to the development of new ionization technologies currently including H3O+, O2+, NO+, Kr+ or Xe+ as selective reagent ions.
H3O+ and NO+, O2+ / Kr+, Xe+ as precursor ions.
Quantify more volatile compounds than ever in real-time with IONICON PTR-MS and SRI-MS technology, using the SRI/SRI+ features, and take advantage of single-digit pptv-level detection limits, only available with IONICON real-time trace gas analyzers.

"The PTR-MS instrument provide us with unique opportunities to investigate dynamic mass transfer processes at low concentrations for a relatively complex chemical composition. We have obtained very useful results related to e.g. emissions of odorous VOC from livestock production and biological air filtration of VOC."
"We use the PTR-MS instrument for both in vitro and in vivo measurements. It constitues an very useful tool to characterize the dynamics of aroma release and to better understand what are the main parameters influencing aroma release, taking product properties and individual physiology into account. It can constitute a first step in better understanding the dynamics of perception."
"We use IONICON Instruments for the measurement of VOCs in mainstream smoke and the exhaled breath of smokers. The PTR-MS is a valuable tool for our research as it allows us to conduct continuous real-time measurements of compounds of interest in a rapidly changing, complex mixture on a puff-by-puff basis."

Identification of active ingredients in seconds without sample preparation Following up our recent research on explosives, chemical warfare agents, toxic industrial compounds and illicit drugs detection, we are currently focusing on the analysis of New Psychoactive Substances (NPS) utilizing state-of-the-art IONICON PTR-TOF 8000 instruments equipped with SRI capability. NPS, or “designer drugs”, “legal highs” and “research chemicals”, […]
