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
