Dissolved species analysis by Membrane Inlet Mass Spectrometry
The HPR-40 DSA provides real-time analysis of dissolved gases in aqueous solutions. Gases and vapours diffuse out of the liquid phase across a polymer membrane and are sampled by a mass spectrometer gas analyser.
Features of the HPR-40 family of DSA systems include:
- A flexible MIMS system with a variety of sampling configurations including a direct insertion probe, continuous flow cells and options for integrated fluid agitation.
- Low gas consumption with static sampling
- Dynamic gas sampling with continuous flow
- Multiport inlet manifold for simultaneous online measurement of several samples
- High sensitivity quadrupole mass spectrometer detection of gas species.
- Continuous data acquisition for real time analysis
Some typical application areas:
- Dimethyl Sulphide (DMS) in seawater
- Respiration and metabolic studies of aquatic organisms
- Pollution studies in lakes, rivers and estuary waters
- Peat and soil core analysis
- Fermentation monitoring and aeration control
- Environmental monitoring.
