浩瀚色谱从定义、分析方法、排放标准中综合性控制指标等角度详细分析了非甲烷总烃(NMHC)与挥发性有机物(VOC_S)之间的关系。从环境管理角度出发,非甲烷总烃涵盖范围越接近挥发性有机物越利于管理,并在实验中选取空玻璃柱作为总烃柱,采用非甲烷总烃的分析原理,定性分析了部分挥发性有机物,根据实验验证结果与非甲烷总烃进行比较,为人们更清晰地认识NMHC和VOC_S之间的关系提供参考。

　　Haohan Chromatography provides a detailed analysis of the relationship between non methane total hydrocarbons (NMHC) and volatile organic compounds (VOCs) from the perspectives of definition, analytical methods, and comprehensive control indicators in emission standards. From the perspective of environmental management, the closer the coverage range of non methane total hydrocarbons is to volatile organic compounds, the more conducive it is to management. In the experiment, an empty glass column was selected as the total hydrocarbon column, and the analysis principle of non methane total hydrocarbons was used to qualitatively analyze some volatile organic compounds. Based on the experimental verification results, a comparison was made with non methane total hydrocarbons, providing a reference for people to have a clearer understanding of the relationship between NMHC and VOCs.
