At the technical preparation for the Offensive Odor Control Law, the measure of the typical illsmelling sulfur compounds, such as hydrogen sulfide, methylmercaptan and dimethylsulfide, were studied. The method adopted is as follows; sample is collected in vacuumed pylex glass bottle (1l or 200ml) with teflon valve cock, and condensed in the cockless GC-sampling tube, cooled by liquid O₂, packed with the same packing materials as GC column, and injected to GC apparatus with FPD, and the concentration of sulfur compounds are determined by calibration curve which is characteristic of 1.74 power. The recovery of the standard samples of a ppb level over 95% was obtained. The reported method was suitable to environmental analysis about the kraft pulp factory.
