PTR-TOF-MS

the new high-resolution, high-sensitivity Proton Transfer Reaction -Time Of Flight - Mass Spectrometer

The PTR-TOF-MS is a combination of the very low online detection limit and the speed of a time of flight mass spectrometer. The TOF component gives the ability to analyze a whole mass spectrum in a split second with a mass resolution of approx. 5000 (FWHM) in V-mode. Further features of this PTR-TOF Mass Spectrometer are a specially W-TOF design combined with the unique proton transfer reaction-ion source, drift tube and inlet system.

• Detection limit: ~ 10 pptv
• Mass Resolution: ~ 5000 (FWHM)
• In one scan all masses are quantified
• Real-time data analysis of full linearity range

Technical Specifications:

• Mass resolution (Benzene, Toluene etc.):	approx. 5000 FWHM (in V-mode)
• Response time:	100 ms
• Sensitivity (Benzene, Toluene etc.):	30 cps/ppbv
• Detection threshold (Benzene, Toluene etc.):	10 pptv @ 1 min 100 pptv @ 1 sec

Specifications are subject to change without prior notice.
