H2S MEDOR : Hydrogene sulfide

H2S MEDOR : Hydrogene sulfide Analyser for continuous on-line monitoring of Hydrogen Sulphide

Description :

H2S Medor is an online Gas Chromatograph dedicated to the analysis of H2S present in different matrices.
Two versions of the instrument exist : 

  • H2S Medor ppm (measuring at ppm levels)
  • H2S Medor ppb (measuring at ppb levels)

Principle :

  • Internal pressure & temperature monitoring
  • Sample loop injection is made by automatic valve
  • H2S Medor uses a sulphur specific electrochemical cell for the detection of H2S

Features :

  • Online, continuous sampling
  • No interference from other compounds
  • Low maintenance instrument – detector life may be up to 10 years
  • Automatic Validation of results by Internal Permeation Tube
  • Modifiable threshold alarms – High / Low alarm for deodorising processes

VISTACHROM ® software 
 Chromatotec developed software system enables :

  • Remote monitoring & injection control
  • Full traceability with on board archiving of results and QC Set up and control of threshold alarms
  • Export of data MODBUS / MGS1 / 4-20mA / 0-10V
