摘要
研究并建立了利用TenaxGC管富集、热解吸仪脱附,经HP-5石英毛细管柱分离,气相色谱(具FID)测定空气,9--硫化碳的方法。研究结果为:当采集30L气体时,本方法检出限可达0.03mg/m3,监测浓度范围为0.03—14mg/m3,方法精密度为8.7%;样品在密闭、低温环境中可保存2d。该方法可以满足环境监测要求。
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.
