Waste water treatment plants and land field

The aim : analyse ppb or ppb of H₂S and mercaptans with the trsMEDOR because of bad smell of exhausts from waste water treatment plants and also the toxicity of H2S and Me-SH.

Usually the four Sulfurs involved in the waste water treatment plants are : (fermentation odor )

► Methylmercaptan(Me-SH), odor+toxic
► Dimethylsulfide (DMS) odor
► DimethylDisulfide (DMDS). odor
► H₂S odor+toxic
► NH₃ and Amines odor

The instruments provided today are total Sulphur analysers that have two major differences with Chromatotec’s solutions. Competitors’ equipments make total sulphur analysis (equivalent in SO₂) whereas we do speciation of all mercaptans compounds at very sensitive levels (down to 1 ppb detection limit ). ppt in option.

The instruments for such applications are mainly the trsMEDOR as it does not require any cylinder gas to work (just carrier gas: AIR or nitrogen by zero air generator) and he is very sensitive intrinsically. Delivered with permeation tube for calibration and validation of results.
