| 摘 要： | 采用预浓缩与气相色谱-质谱联用,建立了垃圾填埋场几种恶臭气体的分析方法。该法用SUMMA罐采集垃圾填埋场臭气,经预浓缩系统冷凝浓缩后,用GC-MS分析测定。几种臭气的检出限均低于3.0×10-3mg/m3,经6次重复测定,其相对标准偏差低于10%。该法已用于西安市江村沟垃圾填埋场臭气的采样分析。该法的应用增强了西安市对臭气的监测分析能力。

| Abstract: | Preconcentration techniques combined gas chromatograph-mass spectrometer was evaluated for landfill gas. Using preconcentration techniques, the range of the lowest detection limits for landfill gas were lower than 3.0×10-3 mg/m3, relative standard deviations (n=6) were generally lower than 10%. The method was applied to determine real sample from Xi'an Jiangcungou landfill, satisfactory results were obtained. |
