The Hiden HPR-40 DSA Membrane Inlet Mass Spectrometer (MIMS) is used for real-time monitoring and quantitative analysis of evolved/dissolved gases.
The compact bench-top gas analysis system is offered with a wide variety of 'DEMS' cells for differential electrochemistry mass spectrometry. DEMS cells comprise of a nano porous membrane interface, allowing rapid response, real-time, in-situ analysis of gaseous and volatile electrochemical reactants, products, and reaction intermediates.
The key features of the Hiden HPR-40 are as follows:
- The system allows analysis down to sub-ppb levels
- A wide range of applications can be addressed, thanks to the presence of both circular membrane carrier inlets and dissolved species probe inlets
- A special membrane is used by the inlet probe that permits small levels of the dissolved species to traverse through it into the ion source of a high precision quadrupole mass spectrometer
- A solenoid safety valve protects the vacuum system and mass spectrometer during failure of a membrane
- A manual isolation valve provides control over the sampling
The Hiden HPR-40 is appropriate for environmental applications requiring low concentration levels and for gas analysis applications requiring small sample volume.
The following are the application examples of the Hiden HPR-40:
- Environmental monitoring
- Monitoring methane production
- Examining fermentation process
- Examining soil core
- Enzyme/microbiological activity studies
- Groundwater contamination research
- Water analysis in river, reservoir or estuary
- Provides high precision and stability species ratio measurements, for instance, in marine de-nitrification studies
- Examination of dissolved species with mass range of 200amu and optional 300amu
