The HSense is based on the Electron Impact 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 particulate 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.
