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
  • Highest precursor ions yields for commercial PTR-QMS
  • 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-MS instrument available in the market* and represents the 4th and most advanced generation of IONICON PTR-MS systems. It is the successor of the world's bestselling PTR-MS system: the IONICON High-Sensitivity PTR-MS, of which various versions and generations are in use all over the world in more than 100 places.

The IONICON High-Sensitivity PTR-QMS 500 continuously quantifies VOCs in lowest possible concentrations touching even the ppqv-regime. The IONICON High-Sensitivity PTR-QMS 500 is our best offer in terms of detection limit, highest sensitivity and precursor ion yields. 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.

It features 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.

The main focus of the PTR-QMS 500 is research or laboratory use being operated using the comprehensive IONICON PTR-QMS series software suite, available on an external notebook computer where the internal touchscreen is used as status indicator.

We provide flexible inlet solutions such as the integrated multi-position capability and the possibility to optionally upgrade the PTR-QMS 500 with multiplexing and data interface units thus bringing down the costs per sampling point and simplifying the integration in existing monitoring network infrastructure.
