Determination of hydrogen sulphide in liquids and gases

The Sulfimax GX Lab fulfils the requirements of the standard DIN 38405-27: German standard methods for the examination of water, waste water and sludge - Anions (group D) - Part 27: Determination of sulphide by gas extraction method (D 27).

Product description

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

The sample can be dosed directly without pretreatment by automated autosampler for liquid samples.

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.

Applications

- 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

Advantages

- Analysis of the original sample
- No sample preparation
- Dosing by autosampler for liquids
- Minimized cross sensitivity through the indirect method

Features and Results

- 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)
