The TRSMEDOR® is an autoGC-ED (MEDOR® Electrochemical wet cell Detector) for the analysis and monitoring of sulfur compounds in air: H2S, Mercaptans, Sulfides.
Two versions exist according to levels of concentration expected:
- The TRSMEDOR® ppm
- The TRSMEDOR® ppb
Principle:
- Automatic sampling using a loop linked to sampling pump
- Automatic loop injection on metallic capillary column
- Isothermal gas chromatograph
- Detection of all compounds eluting from the column performed by MEDOR® Detector: Electrochemical wet cell Detector which is SSD Sulfur Specific Detector.
- Signal provided by reaction between the wet cell electrolyte and the sulfur compounds
Features:
- Automatic calibration/validation of the data, with embedded 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
- No cylinders required thanks to internal calibration tube and gas generators
- Automatic control with process device
- Intelligent 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
Applications:
- WWTP / Refineries / Petrochemicals / Gas process sites
- Ambient / Industrial air monitoring
- Odor impact management
- TRS measurement
