High-Sensitivity PTR-QMS 500

Ultra Sensitive online VOC detector - limit of detection < 1 pptv
Ultra Sensitive online VOC detector - limit of detection < 1 pptv
  • Market-leading ultra low online detection limit 
  • < 1 pptv
  • Real-time VOC quantification
  • Soft ionization technique - low fragmentation
  • Fast and direct sample injection

The High-Sensitivity PTR-QMS 500 is an ultra-sensitive real-time monitor for volatile organic compounds (VOCs) and has a detection limit of < 1 pptv.

The High-Sensitivity PTR-QMS 500 is the most sensitive commercial PTR-QMS instrument available in the market. Its predecessor - the world's bestselling PTR-QMS series, IONICON's High-Sensitivity PTR-MS - is in use all over the world in more than 100 places.

Direct whole air sampling without preparation, straight forward handling and absolute quantification of volatile compounds in real-time is common to all IONICON PTR-MS instruments.

The main focus of the PTR-QMS 500 is research or laboratory use being operated using the comprehensive IONICON PTR-QMS series software suite, but also includes a touchscreen display allowing for one-button control of the system and even preconfigured analysis tasks in combination with an optional embedded industrial computer and individualized software packages.
