TRS Medor - Sulfur Compounds Analyzer

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

• 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

• Automatic calibration/validation of the data, with embeded permeation tube
• 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
• 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

• Multiple stream selector (up to 16 streams with one analyzer)
• Modeling software with weather station for live odor/chemical impact
• Explosion proof version Exp or Exd for ATEX, IECEx zone 1 and 2 and also for CSA C1D2
• Calculation modules (Average / Statistics / Odor unit OU e/m3 and more)
• Automatic data transfer through: Module for 4 outputs 4-20mA / Modbus RTU or TCP IP / MGS1
• Nitrogen or air generator
• 24 V DC power supply
• Electric selection valve to reduce air consumption
• Wall mounted box XXX934

Reduced sulfur compounds analysis:

• Speciation and Total Reduced Sulfur by sum (TRS): H2S, SO2, DMS, MM, DES, DMDS, EM compounds

Detection limits* for H2S, SO2, DMS, MM, EM:

• TRSMEDOR® ppm LDL ≤ 0.1 ppm
• TRSMEDOR® ppb ≤ 1 ppb

*more sensitive analyzers available upon request with special application

Range (adjustable depending on application):

• 0/10 or 0/100 or 0/1000 (ppb or ppm)
• Calculation: Odor Index, Total Sulfur, Total mercaptans

Relative Standard Deviation:

• RSD < 3 % on concentration over 48H
• RSD < 0.5% on retention time over 48H

Cycle Time for the following different analyses:

• H2S, SO2, MM, EM, DMS, DMDS, DES 600s
• With special application following compounds can be added: IPM, TBM, NPM, 2BM, IBM, NBM, MES, THT and THT 1200s
