Ultra-Sensitive - High-Resolution IONICON PTR-TOFMS instrument
Ultra-Sensitive - High-Resolution IONICON PTR-TOFMS instrument

Quadrupole ion guide (Qi)
Detection limit: < 5 pptv

Sensitivity: > 800 cps/ppbv (Benzene)
Mass Resolution: > 5,500



The IONICON PTR-QiTOF continuously quantifies VOCs over the entire mass range in real-time delivering sub pptv-level detection limits in only a few seconds integration time. This PTR-TOFMS series trace gas analyzer has a high mass resolving power, sensitivity and low detection limit.

Using an orthogonal acceleration reflectron time of flight (TOF) mass spectrometer with a Quadrupole ion guide (Qi) in combination with the IONICON PTR technology and our ULTRA-PURE ion source the PTR-QiTOF achieves a mass resolution of more than 5,500 (m/Δm FWHM) and nevertheless reaches a limit of detection well below 5 pptv (in 60 sec) and sensitivity of more than 800 cps/ppbv for Benzene.

Sounds good?
Then you should check out our brand new premium model: PTR-TOF 6000 X2. Benefit from even more performance based on our compact ioniTOF platform.
