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 HSense is available with unique and fully automated gas inlet systems in order to compensate pressure variations, optimize the amount of withdrawn sample gas and thus guarantees the correct measurement.
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.
