The Sulfimax GX Lab fulfils the requirements of the German standard DIN 38405-27: Determination of sulphide by gas extraction method (D 27)

The Sulfimax GX Lab determines hydrogen sulphide (H2S) and volatile sulphides in liquids and gases.

The sample can be dosed directly without pretreatment - manually by syringe or in the automatic version by autosampler.

By effective gas extraction the H2S is completely expelled from the sample. Interferences due to the sample matrix practically do not occur.

The released H2S gas is conducted to the highly sensitive sensor, which detects H2S in the range of 0.01 to 10,000 ppm. A typical measurement takes 5 min, depending on the sample composition.

If the Sulfimax GX Lab is extended with the optionally available H2S Headspace Module, solid and pasty samples can also be measured.



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


  • Analysis of the original sample
  • No sample preparation
  • Dosing manually or optional fully automatic
  • Minimized cross sensitivity through the indirect method


  • Complete separation of H2S from the sample by effective gas extraction
  • Simple calibration
  • Software: simple, clear, intuitive
  • Definition of own methods for device control
  • Typical measuring time 5 min (depending on sample properties)
