Online analysis and monitoring of odorous sulfur compounds

The airmoMEDOR® is an automatic gas chromatograph (autoGC) for the analysis and monitoring of trace amounts of Methyl-Mercaptan, Ethyl-Mercaptan, Di-Methyl-Sulfide, Di-Methyl-Di-Sulfide and Di-Ethyl-Sulfide by electrochemical wet cell detection (MEDOR® technology).

The airmoMEDOR® can be used for :

  • monitoring of urban and non-urban pollution
  • monitoring of industrial nuisance
  • deodorization process
  • fugitive emission
