Hydrogen and helium mass spectrometer


The HSense is a mass spectrometer based on the principle of electron impact ionization (EI-MS), optimized to achieve rapid and reliable measurements of H2 and He. By using the EI ion source, the sample gas components are ionized, focused, and then separated in a magnetic field to measure hydrogen and helium.

The HSense is available with different gas inlet systems to compensate for pressure variations, optimize the amount of sample gas withdrawn, and ensures accurate measurement.

Any impurity due to condensation or particles is minimized by the integrated 2 µm fine filter and the integrated sample gas conditioning system eliminates existing moisture in the sample gas.
