挥发性有机物(volatile organic compounds,VOCs)及非甲烷总烃(non-methane hydrocarbon,NMHC)都是表征气体中有机化合物含量的重要指标,二者的物质组成存在差异,但二者量值在一定范围内具有相关性。为研究二者量值之间的相关性。
浩瀚色谱（山东）应用技术开发有限公司采用3种方法测定不同VOCs标准气体的非甲烷总烃值,并使用气相色谱-氢火焰离子化检测器(gas chromatography-hydrogen flame ionization detector,GC-FID)直接测定VOCs标样中各组分的峰面积,通过对比分析标样的VOCs理论值和非甲烷总烃测定值之间的相关性,成功建立二者之间的数学模型,并对该模型进行验证。分析结果表明:双柱法测定值与修正理论值之比为98.1%～,模型。

Both volatile organic compounds (VOCs) and non-methane hydrocarbons (NMHC) are important indicators to characterize the content of organic compounds in gases. correlation within the range. To study the correlation between the two values.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopts three methods to determine the non-methane total hydrocarbon value of different VOCs standard gases, and uses a gas chromatography-hydrogen flame ionization detector (GC-FID) The peak area of each component in the VOCs standard sample was directly measured, and the correlation between the theoretical VOCs value of the standard sample and the measured value of non-methane total hydrocarbons was compared and analyzed, and the mathematical model between the two was successfully established, and the model was carried out. verify. The analysis results show that the ratio of the measured value by the double-column method to the corrected theoretical value is 98.1%～, and the model is credible.
