H2S/TOS TS MEDOR® : H2S, total organic sulfur and total sulfur

H2S/TOS TS MEDOR® : H2S, total organic sulfur and total sulfur The H2S/TOS TS MEDOR® is an autoGC-ED (MEDOR® Electrochemical wet cell Detector) for the analysis and monitoring of H2S, TOS and TS.
  • Different configurations exist depending on the application and concentration range : HS2/TOS TS MEDOR ppb for 0-1 ppm and H2S/TOS TS MEDOR ppm for 0-10 / 0-50 / 0-100 ppm
  • Automatic sampling using a loop
  • Automatic loop injection on metallic capillary column
  • Isothermal gas chromatograph
  • Detection of all compounds eluting from the column performed by MEDOR® detector : Electrochemical wet cell Detector which is a Sulfur Specific Detector (SSD)
  • Signal provided by electrochemical reaction between the wet cell electrolyte and the sulfur compounds
  • Fully compliant with ASTM D 7493-14 : Standard Test Method for On-line Measurement of Sulfur Compounds in Natural Gas and Gaseous Fuelsby Gas Chromatograph and Electrochemical Detection.
  • Compliant with ASTM D 5504-20 : Standard Test Method for Determination of Sulfur Compounds in Natural Gas and Gaseous Fuels by Gas Chromatography and Chemiluminescence with alternative detector.
Key points
  • Continuous monitoring with automatic online sampling
  • Analytical performances :
    - Specific, linear and very sensitive to sulfur compounds
    - Results validation by automatic standard injection
    - Long term stability using detector installed in reservoir
  • Extremely low maintenance :
    - Very long life time detector with electrolyte, up to 10 years.
    - Low gas consumption, can be reduced in option
    - More than 10 years data storage
    - No cylinders required thanks to internal calibration tube and gas generators
  • Automatic control with process device
  • Intelligents system with tunable and interactive alarm levels
  • Powerful VISTACHROM Chromatotec® software :
    - Remote monitoring & injection control
    - Full traceability with on board archiving of results and chromatograms
