DETERMINATION OF TOTAL HYDROCARBON IN ATOMSPHERE BY GAS CHROMATOGRAPHY

摘要: 本文叙述了采用直接进样气相色谱测定大气中总烃(C1—C8)的方法;采用氢火焰离子化检测器,并以除烃空气作为载气和助燃气。方法的相对标准偏差为3.8%,最低检出限为0.1mg/m3(以甲烷计)。应用本方法,对大庆市大气样品中的总烃进行了测定,效果良好。

Abstract: Determination of total hydrocarbon by direct injection GC, equipped with a hydrogen flame ionization detector. Hydrocarbon-free air was used as carrier gas, also as combustion-supporting gas. The relative standard deviation and minimum detection limit of the method were found to be 3.8% and 0.1mg/m3 for CH4, respectively.
