H2S/TOS TS MEDOR - Sulfur Compounds Analyzer

According to the level of concentration several versions exist:

• Standard with the loop 10μL and bypass for the range 0-15ppm of H2S and above 50ppm TS
• With the loop 50μL for the range 0-3ppm of H2S and > 10ppm TS

• 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 MEDOR’s wet cell sulfur specific detector
• Signal provided by electrochemical reaction between the wet cell electrolyte and the sulfur compounds

• Automatic calibration/validation of the data, with embeded permeation tube (optional)
• Continuous monitoring with automatic online sampling
• Analytical performances:
• Specific 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, up to 10 years.
• No need to change the electrolyte for at least 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
• QC Set up and control of threshold alarms
• Data export by MODBUS / 4-20 mA / 0-10 V
• Time stamp results
