Analysis of Sulfur Compounds in Air
Problems of odor emissions from local paper plant
Analysis of sulfur compounds in ambient air at ppb levels is requested.
Client has SO2 analyzer in situ, showing levels of approx 0-10 ppb in general.
The concentration variations of SO2 for our analyzer and the current system followed the same trend throughout the 10 days period.
However, our TRS Medor has a much higher response to SO2 which is seen in the higher concentration values obtained.
Unlike the competitor, our TRS Medor offers measurement & speciation of other sulfur compounds :
In this instance :
- Methyl-mercaptan (Me-SH)
- Ethyl-mercaptan (Et-SH)
- Hydrogen sulphide (H2S)
- Di-methylsulphide (DMS)
- Di-methyl di-sulphide (DMDS)
From the results obtained, we have found that not only SO2 was present, but also other harmful Sulfur species which are causing the high odor levels in the area.
