Description :
The MEDOR ® Exd is an industrial gas chromatograph for the analysis
and monitoring of sulfur compounds in natural gas and gaseous fuels:
H2S, Mercaptans, Sulfides.
Two versions exist: ppm range or ppb range
Principle:
• Automatic sampling using a loop
• Loop injection by automatic valve on the column
• Isothermal gas chromatograph
• Detection of all compounds eluting from the column performed by
Chromatotec's wet cell sulfur specific detector
• Signal provided by electrochemical reaction between the wet cell
electrolyte and the sulfur compounds
Key points:
• Fully compliant with ASTM D 7493-08 : Standard Test Method for On -
line Measurement of Sulfur Compounds in Natural Gas and Gaseous
Fuels by Gas Chromatograph and Electrochemical Detection
• Internal automatic calibration system allowing automatic validation of
the data
• Continuous monitoring with automatic online sampling
• Analytical performances:
• Specific and very sensitive to sulfur compounds
• Results validation by automatic standard injection at each analysis
• Long term stability using wet cell detector installed in reservoir
• Extremely low maintenance
• Very long life time detector, up to 10 years including elctrolyte
• Low gas consumption, can be reduced in option
• More than 10 years data storage
• No calibration cylinders required thanks to internal calibration tube
• Automatic control with process device
• Intelligence system with tunable and interactive alarms levels
• Internal temperature and pressure monitoring
• Powerfull VISTACHROM Chromatotec ® software: • Remote monitoring & injection control• Full traceability with on board archiving of results and chromato - grams• QC Set up and control of threshold alarms• Data export by MODBUS / 4-20 mA / 0-10 V• Time stamp results• On site direct access to the analyzer with LCD screen and touch pad on front panel
