High sensitivity, in-water detection and analysis.

Monitoring of water quality is a key issue worldwide. The provision of clean, safe drinking water is important to all communities, everywhere. AquaMMS is a portable mass spectrometer capable of monitoring the purity of water in to extremely high sensitivities. The instrument can be used by a non-specialist operator at the point of measurement or addressed remotely over the internet.

The enabling technology in AquaMMS is a robust and portable miniature mass spectrometer (MMS), which can monitor online a wide range of water quality indicators simultaneously. Dissolved gases (e.g., O2, CO2, N2, Total Gas Pressure, H2S), Volatile Organic Compounds (e.g., CH3SCH3, Benzene, Toluene, Xylene, and other BTEXs) can all be monitored to part per billion (ppb) sensitivities.


Monitors the following dissolved species in water:

  • O2
  • CO2
  • N2
  • H2S
  • CH3SH3
  • Benzene
  • Toluene
  • Xylene
  • other BTEXs and VOCs
