Why IONICON PTR-TOF / PTR-MS instruments?

  • PTR is a very efficient and soft ionization method leading in high sensitivity and low limit of detection, little to no and adjustable fragmentation
  • PTR-MS does not require pre-separation, such as GC, nor sample preparation
  • PTR-TOF instruments analyze in real-time and deliver exact concentrations within sub-seconds
  • PTR-TOF instruments have proven high mass resolution and high sensitivity over a broad mass range
  • PTR-TOF instruments can analyze hundreds of organic and inorganic compounds, which can be extended by SRI (Selected Reagent Ions)
  • IONICON instruments are known to be robust and reliable - the MTBF of our instruments is > 24 months
  • In contrast to other manufacturers IONICON's PTR-TOF employ well-defined ion chemistry conditions and patented TRU-E/N technology

IONICON PTR-MS for all applications

IONICON PTR-MS instruments are fast, sensitive, accurate and extremely robust. Our customers deploy them all over the world in various environments: From the Amazon rain forests to the Arctic, from petrochemical plants to hospitals, in semiconductor clean-rooms and on mobile platforms, such as mobile labs and even aboard NASA aircrafts. Please see our application case studies for more details.
