The Sulfimax GX Lab fulfils the requirements of the German standard DIN 38405-27: Determination of sulfide by gas extraction method (D27)

The Sulfimax GX Lab determines hydrogen sulfide (H₂S) and volatile sulfides 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)
