摘要
环境空气应急监测中,采用车载GC/MS热脱附法测定挥发性有机物,可直接现场采样分析,方法线性良好,44种化合物的检出限为1.2 ug/m3~9.7 ug/m3,标准气体平行测定的RSD≤9.0%。
In case of ambient air emergency monitoring,with the method of thermal desorption- onboard GC / MS to determine volatile organic compounds,it could on- site sample directly and also with good linear optimal method to determine,detection limits of 44 compounds between 1. 2ug / m3 and 9. 7 ug / m3,RSD of parallel standard air ≤9. 0%.
