Description:
• THT MEDOR® is an autoGC-ED (MEDOR® Electrochemical wet cell Detector) for the analysis and monitoring of THT and TBM in natural gas and gaseous fuels.
Principle:
• Automatic sampling using a loop
• Automatic loop injection on packed column
• Isothermal gas chromatograph
• Detection of THT and TBM eluting from the column performed by MEDOR®
Detector:Electrochemical wet cell Detector which is SSD Sulfur Specific Detec -
tor.
• Signal provided by reaction between the wet cell electrolyte and the sulfur
compounds
KeyPoints:
• 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.
• Automatic calibration/validation of the data, with embeded permeation tube
• 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 : full chromatogram
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 & injec -
tion 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
Options:
• Multiple stream selector (up to 32 streams with one analyser)
• Explosion proof version Exp or Exd for ATEX, IECEx zone 1 and 2 group IIC T4
and also for CSA C1D2 group B , C & D T4
• Calculation modules (Average / Statistics / Odor index and more)
• Automatic data transfert through: Module for 4 outputs 4-20 mA (with 0 mA for
instrument default) / 0 - 10 V / MODBUS RTU or TCPI IP or MGS1
• Nitrogen or air generator for safe and hasardous area
• 24 V DC power supply
• Electric selection valve to reduce air consumption
• Liquid injection valve from LPG up to condensates
• High concentration injection valve up to 5%
• Wall mounted box XXX934
• Liquid injection valve for LPG analysis
• Touch screen on the front panel for Exp version (only ATEX)
• External cylinder inlet for automatic calibration from external cylinder
• MFC for multipoint calibration from internal CALIB and/or from cylinder
• Zero method
