Determination of hydrogen sulphide in liquids and gases

Sulfimax GX Lab - analysis system for H2S determination in liquids and gases (Laboratory version)
Sulfimax GX Lab with Headspace Module and autosampler for liquids

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.

 

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 manually or optional fully automatic
• Minimized cross sensitivity through the indirect method

Features

• 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)
