The aim : analyze ppb or ppb of H2
S and mercaptans with the TRSMEDOR
because of bad smell of exhausts from waste water treatment plants and also the toxicity of H2
S 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 Sulfur analyzers that have two major differences with Chromatotec’s solutions. Competitors’ equipments make total sulfur analysis (equivalent in SO2
) whereas we do the 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 gas cylinder to work (just carrier gas : AIR or nitrogen by zero air or nitrogen generators) and he is very sensitive intrinsically. Delivered with permeation tube for calibration and validation of results.
