H2S MEDOR TRACE H2S(0-1) in Hydrogen

Description:

The H2S MEDOR® is an autoGC-ED (MEDOR® Electrochemical wet cell Detector) for the analysis and monitoring of H2S in natural gas and gaseous fuels.

Three versions exist:

• H2S MEDOR® ppb for 0 – 1 ppm

• H2S MEDOR® ppm for 0-10 / 0-50 / 0-100 ppm

• H2S MEDOR® % for 0-10 %

Principle:

• Automatic sampling using a loop

• Automatic loop injection on column

• Isothermal gas chromatograph

• Detection of H2S eluting from the column performed by MEDOR® Detector:Electrochemical wet cell Detector which is SSD Sulfur Specific Detector.

• Signal provided by electrochemical reaction between the wet cell electrolyte and the sulfur compounds

Key points:

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.

Continuous monitoring with automatic online samplin

Analytical performances:

• Specific, linear and very sensitive to H2S

• Results validation by automatic standard injection
