H2S ANALYZER Lab with Head Space Module and autosampler  
H2S ANALYZER Lab with Head
Space Module and autosampler
for liquids		  

The H2S ANALYZER Lab fulfils the requirements of the standard DIN 38405-27:2017-10: Determination of sulphide by gas extraction method (D 27)

The H2S ANALYZER Lab measures hydrogen sulphide in liquids and gases in only one device.

The determination of total volatile sulphides in aqueous solutions and other liquid samples works through high efficient gas extraction linked with a selective detection method. Thereby, interferences from the sample matrix will be minimized.

The analysis is performed fast and with high efficiency. Sample preparation is not required, therefore the reproducibility and the accuracy enhance additionally.

The dosing of the sample can either happen manually using syringe or optionally using an automated autosampler.

For extension of application the device can be upgraded with an additional Head Space Module. It is suitable for solid and pasty samples.

Principle of measurement

  • Dosing of the sample via syringe or autosampler into the gas extracting vessel
  • Fast release of the H2S out of the sample after automatic addition of the acid
  • Automatic transfer of the H2S onto the electrochemical sensor
  • Automatic integration of the measurement graph
  • Results in parts per million (ppm), milligrams (mg/L) or, if requested, in customer specific units by using a formula creator

Advantages

  • Complete separation of H2S from the sample
  • Analysis of the original sample
  • No sample preparation
  • Simple calibration
  • Software: simple, clear, intuitive
  • Dosing manually or optional fully automatic
  • Definition of own methods for device control
  • 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
