Compact version "H2S ANALYZER Cubi"  
Compact version "H2S ANALYZER  Cubi" for laboratory and on-site use  
   
Compact version "H2S ANALYZER Cubi" with Head Space Module  
Compact version "H2S ANALYZER Cubi" with Head Space Module for analysis of solid samples  

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

The H2S ANALYZER Cubi 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 is carried out manually with a syringe.

Thanks to its compact design the H2S ANALYZER Cubi is suitable also for on-site use. 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 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
  • 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
