Determination of hydrogen sulphide

The determination of total volatile sulphides in aqueous solutions and oils works through high efficient gas extraction linked with a selective detection method.

The H2S Analyzer creates the opportunity for analysis of hydrogen sulphide in gases and liquids in only one device.

The determination of volatile hydrogen sulphide in solid and high viscous samples is easily feasible by using a manual Headspace Module coupled with the selective H2S-Analyzer.

The OnlineH2S for gases is suitable for continuous monitoring of H2S over waste waters. This makes chemical treatment that meets the demand of waste water possible.


  • Sewage analysis
  • Monitoring of landfill-leachate
  • H2S in hydrocarbon mixtures, e. g. mineral oil, transformer oil
  • Environmental applications
  • Gas analysis
  • Investigation of technical and pharmaceutical products (e. g. storage stability)
  • Quality management


  • Electrochemical sensor for precise, reproducible and  sensitive micro-analysis
  • Complete separation of H2S from the sample
  • Fully automated analytical procedure
  • Analysis of the original sample
  • No sample preparation
  • Definition of own methods for device control
  • Simple calibration
  • Dosing manually or optional fully automatic
  • Minimized cross sensitivity through the indirect method
  • Gas extracting technique for a fast release and separation of H2S from the sample
  • Robust and fast analysis
  • Software: simple, clear, intuitive
