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 an IONICON exclusive technology allowing to automatically switch between different reagent ions for chemical ionization direct injection mass spectrometry. Currently the the range of selective reagent ions includes H3O+, O2+, NO+, NH4+, Kr+ or Xe+.

"The PTR-TOF-MS from IONICON will allow us to measure a wide range of VOCs in ambient air and in chamber studies. We chose the PTR-TOF 4000 for its sensitivity and high temporal resolution. The instrument's small size and reliability simplify field deployment."
"We use the PTR-TOF 6000 X2 for characterizing liquids in real time with excellent time resolution. The speed and sensitivity of IONICON’s trace gas analyzer enables us to monitor liquid products of electrochemical reactions (e.g.alcohols, aldehydes, ketones, organic acids, etc.) at the time they are formed..."
“We conduct both laboratory and field-based experiments with the aim of unravelling how climate change impacts the ecosystem-atmosphere exchange of biogenic VOCs...In these studies, it is vital to be able to track changes in the VOC blend and concentration in real-time with our PTR-ToF-MS instruments. The compact size and mobility have allowed us to bring our sensitive PTR-TOF 1000 ultra instruments to the Arctic tundra to measure ecosystem fluxes of VOCs.”

Bulk Organic Aerosol Analysis by PTR-MS with High Precision & Accuracy Very recently, we have published a technical note in Analytical Chemistry introducing an improved methodology for the determination of organic aerosol properties with CHARON PTR-TOFMS. By analysis of a large set of pure compounds we were able to derive an algorithm to correct for ionic fragmentation. […]
