Determination of hydrogen sulphide

Determination of hydrogen sulphide

For the summary determination of highly volatile sulphides in aqueous solutions and oils, we have coupled a highly effective gas extraction with a selective detection method.

For hydrogen sulphide analysis we offer the H2S analyzer Sulfimax GX in the laboratory version Lab and in the compact version Go. With both versions, H2S can be determined in gases as well as in liquids.

An autosampler for liquid samples is available for the Sulfimax GX Lab. Due to its compact design, the Sulfimax GX Go requires less floor space in the laboratory and is suitable for on-site applications.

An external H2S Headspace Module can be connected to both versions to measure hydrogen sulphide in solid samples as well.

The online analysis system Sulfimax GX online GAS is suitable for continuous monitoring of H2S in the airspace above wastewater. This makes it possible to dose wastewater treatment agents as needed.

Applications of the H2S analyzer Sulfimax GX Lab or Go

  • Water, drinking water, surface water
  • Municipal waste water
  • Industrial wastewater
  • Landfill leachate monitoring
  • Gas analysis (e. g. LNG, LPG)
  • H2S in hydrocarbon mixtures
  • Analysis of technical and pharmaceutical products (e. g. storage stability)
  • Quality management


  • Analysis of the original sample
  • No sample pre-treatment
  • Sample dosing manually or automatically via autosampler (optional for lab version)
  • Extremely low cross-sensitivities due to indirect method


  • Complete separation of H2S from the sample by effective gas extraction
  • Simple calibration
  • Simple, clear software
  • Definition of own measuring methods for instrument control
  • Typical measuring time 5 min (depending on sample composition)
