Abstract
Gas chromatography coupled with the sulfur specific flame photometric detector has been used as the basis for developing an analytical system with sensitivity in the ppb (ml odorant/ml air) range for organosulfur compounds. A high vacuum line for storage and handling of standard compounds, and the use of gas syringes are integral features of the calibration system. Sampling equipment has been constructed and tested which allows the analysis of gaseous organosulfur compounds in wastewaters, sewer gases and ambient air. Gaseous mixtures have been found to keep better than aqueous solutions with respect to microbiological, chemical, or physical losses. The analytical system was employed to trace and characterize an odor incident from a municipal treatment plant to the industrial discharger causing the problem. Analytical data have shown that certain long-chain mercaptans which are not normally odorous can decompose in aeration treatment facilities to produce low molecular weight mercaptans which then cause an odorous condition.
