Proven Technology :

Robustness and reliability together with proven components for gas inlet and vacuum system, optimized serviceability and a mini-mum of operational cost reflect more than 25 years of experience within the field of the mass spectroscopy. Combining well proven techno-logy with our unique and highly dynamic sampling system, the HSENSE.net offers a reliable low maintenance operation.

The measurement principle is based on the sector field mass spectroscopy, optimized to measure fast, dynamic and online the mass range of 2-4 amu with the overall response time less than 1 sec.

Stand Alone or Combined Applications :

As a stand alone machine, or with the ideal combi-nation together with our well proven IMR mass spectrometer AIRSENSE.net, applications range from emission control to landfill monitoring, from fuel cell to sensor R&D and engine test benches.

Our user friendly software package takes over all systems set up and data reporting issues.

Principle of Operation :

Targeting the specific needs within the applications, the series HSENSE.net is based on the Electron Pulse Ionization (EIMS) Mass Spec principle optimized to measure H2 and He fast and reliably. By using the electron ion source the gas sample ions are energized, focused and separated further on in a magnetic field in order to detect Hydrogen and Helium. The unique and fully automated gas inlet system compensates for pressure variations in between 500 mbar and 3 bar. The system guarantees the correct measurement and avoids any discrimination of the gas. Any contamination due to condensation or par-ticulate matters is minimized by the integrated 2 micron fine filter in combination with a cross flow sample conditioning system, which takes care of any potential water content.
