Ultra-Sensitive Real-Time Trace Gas Analyzers  •  Modular TOF-MS for Research & OEM

PTR-QMS Performance Data
Market-leading online detection limits for VOCs reaching ppqv-level with ULTRA-PURE ion source. The best available detection limits for online trace gas analysis now also with H3O+, NO+ and O2+ as precursor ions.
The Analyzer for your Analytical Instrument
Quadrupole or time-of-flight mass spectrometer Since 1998 IONICON produces and develops PTR-MS instruments. Nowadays nearly all our analytical instruments are based on a TOF-MS. Learn why and decide what type of detector is the best for your analytical objective. Here are some tips which might help you to decide what type of detector is the best for your analytical objective:
The technologies we use in our solutions: PTR-MS, SRI-MS, SRI+...

"Our group uses Ionicon PTR-MS and PTR-QiTOF instruments to study the sources, chemistry, and impacts of atmospheric organic compounds across a diverse range of environments. We use these instruments because the combination of sensitivity, mass resolution, and fast time response provides an important toolset for our research."
"At Wageningen UR we see many research applications for the IONICON PTR-QiTOF. It’s easy use, sensitivity, accuracy and on line detection without the need of prior treatments makes it a high potential instrument for all kinds of diagnostic and quality oriented research, going from environmental issues, to food and to health biomarkers."
"We use IONICON PTR-MS and PTR-TOFMS instruments for real-time measurements of a broad array of VOCs in the atmosphere, including ecosystem and aircraft scale flux measurements, direct emissions from plants and microbial cultures, controlled laboratory oxidation studies of VOC reactions and secondary aerosol formation, and field studies of atmospheric chemistry and air pollution. The rapid response and low detection limits made possible by these instruments are critical to our scientific investigations."


Custom-built by IONICON engineers for the University of Montana One of the special skills we are known for is to custom-build PTR-TOFMS and ioniTOF systems for research and industrial applications. Our engineering team is eager to work out special solutions and by now we have a solid track record for more than two dozen tailor-made […]
