Description:

The H2S MEDOR® is an autoGC-ED (MEDOR® Electrochemical wet cell Detector) for the analysis and monitoring of H2S in natural gas and gaseous fuels.

Three versions exist: • 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 7493-14 : 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

Powerfull VISTACHROM Chromatotec® software:

• Remote monitoring & injection control

• Full traceability with on board archiving of results and chromatograms

• QC Set up and control of threshold alarms

• Data export by MODBUS

• Time stamp results
