H2S/TOS TS MEDOR® : H2S, total organic sulfur and total sulfur

The H2S/TOS TS MEDOR® is an autoGC-ED (MEDOR® Electrochemical wet cell Detector) for the analysis and monitoring of H2S, TOS and TS.
- Different configurations exist depending on the application and concentration range : HS2/TOS TS MEDOR ppb for 0-1 ppm and H2S/TOS TS MEDOR ppm for 0-10 / 0-50 / 0-100 ppm
Principle
- Automatic sampling using a loop
- 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 a Sulfur Specific Detector (SSD)
- Signal provided by electrochemical reaction between the wet cell electrolyte and the sulfur compounds
- Fully compliant with ASTM D 7493-14 : Standard Test Method for On-line Measurement of Sulfur Compounds in Natural Gas and Gaseous Fuelsby Gas Chromatograph and Electrochemical Detection.
- Compliant with ASTM D 5504-20 : Standard Test Method for Determination of Sulfur Compounds in Natural Gas and Gaseous Fuels by Gas Chromatography and Chemiluminescence with alternative detector.
