摘要
本文建立了苏马罐-预浓缩-气相色谱质谱联用系统同时分析大气中117种挥发性有机物的方法,确定了预浓缩仪、气相色谱及质谱仪的参考条件.该方法的检出限、线性相关性、精密度等方法学指标均能满足HJ759方法及《2018年重点地区环境空气挥发性有机物监测方案》附录的要求,能够满足环境空气中挥发性有机物的监测需求.
In this paper,a method for simultaneous analysis of 117 volatile organic compounds in the atmosphere by tank sampling-preconcentration-gas chromatography mass spectrometry system was established,and the reference conditions of pre-concentrator,gas chromatography and mass spectrometer were determined.The methodological indicators such as detection limit,linearity and precision of this method can meet the requirements of HJ759 method and the appendix of the《2018 Air Volatile Organic Compounds Monitoring Program in Key Areas》,and can meet the monitoring needs of atmospheric volatile organic compounds.
