Dissolved Species Analysis

Dissolved species analysis employing Hiden's high sensitivity membrane sampling technology for analysis of respiratory gases, hydrocarbons and sulphides is applied to a wide range of application areas including:

  • Ecolological studies in sea water
  • Bio fuel production from algae
  • Pollution monitoring in river, estuary and reservoir waters
  • Soil core analyses
  • Fermentation



Dissolved species analysis system.

HPR-40 DSA.- A gas analysis system for analysis of gases, vapours and VOCs in liquids

  • Soil core analysis
  • Fermentation Process Analysis
  • Water Analysis in Estuary, River or Reservoir
  • Groundwater Contamination Studies
  • Methane Production Control
  • Microbiological / Enzyme activity studies
  • Environmental monitoring

The HPR-40 dissolved species gas analysis system is a compact bench-top gas analysis system for monitoring of dissolved / evolved gases, featuring:

  • Compact bench-top / mobile cart / console rack construction.
  • High Sensitivity (to 5 ppb), Mass range options 200, 300 or 510 amu.
  • Fast valve dissolved species probe incorporating permeable silicone membrane.
  • Membrane re-circulation cell option for extended, dynamic studies.
  • Penning Gauge and interlocks to provide over pressure protection.
  • Fast action automatic shut off valve in case of probe failure.
  • Ioniser liquid N2 cryopanels for optimum vacuum / minimal spectral interference.
  • Vacuum manifold isolation gate valve for fast start up at remote locations.
  • Stability (less than ±0.5% height variation over 24 h).
  • MASsoft control via RS232, RS485 or Ethernet LAN.
  • Soft Ionisation for the analysis of complex organics / appearance MS studies.
  • 4 or 8 way multiplexed inlet for sampling from multiple probe
