| Abstract: | The carbon bisulfide in polluted air was determined by an disorption system and gas chromatography （FID） with HP- 5 capillary column. When the 30 L air captured, the detection limit of this methed was 0.03 mg/m^3 . In the concentration range of 0.03 14 mg/m^3 , definition was 8.7 % - Under darkness and low temperature, the sample could be on seability for 2 days. |
