抄録

The gas chromatographic analysis of the trace concentrations of sulfur compounds at the level of ppb or ppt in the urban air was studied.<BR>The sample for the gas chromatographic analysis was prepared by the direct cold trap method cooled with liquid oxygen, and then detected by the flame photometric detecter.<BR>Four sulfur compounds, i.e. hydrogen sulfide, carbonyl sulfide, sulfur dioxide and carbon disulfide were identified with the use of TCP and TCEP columns. One month's survey (Apr. 5Apr. 30, 1974, 100 samples) showed that the detected concentration ranges and average values of the four sulfur compounds were as follows: hydrogen sulfide 0.524 ppb (av. 2.4 ppb), carbonyl sulfide 0.42.9 ppb(av. 1.2 ppb), sulfur dioxide 2.080 ppb (av. 22 ppb) and carbon disulfide 0.175 ppb (av. 2.7 ppb), respectively.<BR>The minimum detectable concentrations of the method were as follows: about 200 ppt for hydrogen sulfide and sulfur dioxide, about 50 ppt for carbonyl sulfide and carbon disulfide.
