Capabilities

  • Direct measurement of dissolved N2, O2, and Ar concentrations in environmental water samples
  • Small sample sizes (3+ ml)
  • Does not require headspace equilibration
  • Analysis time of 90 seconds per raw water sample, typical
  • Precision of dissolved N2, O2, and Ar measurements (triplicate samples): 0.1%
  • Precision of gas ratio (N2/Ar and O2/Ar) measurements (triplicate samples): 0.03%
  • Detects stable isotopes
  • Automatic recording of dissolved gas trends in ‘strip chart’ mode
  • Can be applied to CO2, CH4, DMS, and other low molecular weight dissolved gases
