Proton Transfer Reaction - Mass Spectrometry
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. We're the market-leading PTR-MS company.
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.

"We use a PTR-TOF-MS to study the chemistry and emission of VOCs focusing on wildfires and land-atmosphere exchange. The custom-built instrument allows us to carry out the trace gas concentration and flux measurements on a research aircraft and on the ground with outstanding response time, mass resolution, and sensitivities."
"The IONICON PTR-TOF-MS is a recognized gold standard in the trace gas analysis of complex mixtures. Therefore, we use it as calibration and validation device for our novel gas sensors for breath analysis."
"We are studying VOCs and their chemistry in the atmosphere. These VOCs from various sources are often present in very low concentrations therefore we need an instrument with a low detection limit. One important part of our research is the biosphere atmosphere interaction. We measure e.g. plants emissions. Plants emit a wide variety of VOCs which demands an analyzer able to cover a broad mass range in a short period of time. The IONICON PTR-TOF 4000 allows for simultaneous measurements of many VOCs with high sensitivity at high temporal resolution."

At the Frontier of Airborne Research aboard NASA’s Flying Laboratory Using the opportunity provided by NASA’s Student Airborne Research Program (SARP) we gave wings to our newly developed CHARON aerosol inlet. In cooperation with the University of Oslo our team combined CHARON and a custom built PTR-TOF 4000 instrument. Airworthiness requires withstanding of heavy G-forces, […]

IONICON-grade PTR-MS Quality: Important Ion Chemistry Dimensions You’ve got used to expecting an IONICON-grade instrument when you see the abbreviation “PTR-MS“? After all, more than 350 IONICON PTR-MS instruments yielded hundreds of high-impact papers and allowed gaining insights in various science domains. But, what determines a real IONICON PTR-MS and how does it compare to other CIMS […]
