使用芯片式流路气相色谱-质谱联用仪分析土壤中的半挥发性有机化合物

Analysis of Semivolatile Organic Compounds in Soil Using a Flow-on-Chip Gas Chromatography-Mass Spectrometry

气质联用系统是分析环境样品中的半挥发性有机化合物的常规分析仪器。使用带有芯片式流路的气质联用仪根据USEPA方法8270D的性能指标来分析半挥发性化合物,通过重复进样复合土壤提取物并在模拟高通量环境实验室条件下评估了测量仪器的耐用性和重复性。

GC-MS is a conventional analytical instrument for the analysis of semi-volatile organic compounds in environmental samples.This paper uses a GC/MS with a flow-on-chip to analyze semivolatile compounds according to the performance specifications of USEPA Method 8270D,by repeatedly injecting composite soil extracts and evaluating the measurement instrument under laboratory conditions that simulate high-throughput environments durability and repeatability.
