H2S MEDOR

• H2S MEDOR® ppb for 0 – 1 ppm
• H2S MEDOR® ppm for 0-10 / 0-50 / 0-100 ppm
• H2S MEDOR® % for 0-10 %

Principle:

• Automatic sampling using a loop
• Automatic loop injection on column
• Isothermal gas chromatograph
• Detection of H2S eluting from the column performed by MEDOR® Detector:Electrochemical wet cell Detector which is SSD Sulfur Specific Detector.
• Signal provided by electrochemical reaction between the wet cell electrolyte and the sulfur compounds

Key points:

Fully compliant with ASTM D 7493-22 : Standard Test Method for Online Measurement of Sulfur Compounds in Natural Gas and Gaseous Fuels by Gas Chromatograph and Electrochemical Detection.

Continuous monitoring with automatic online sampling. Analytical performances:

• Specific, linear and very sensitive to H2S
• Results validation by automatic standard injection
• 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 : full chromatogram
• No cylinders required thanks to internal calibration tube and gas generators
• Automatic control with process device
• Intelligence system with tunable and interactive alarms levels
