固定污染源废气中NMHC与VOCs监测总烃毛细管柱HH-THC-30

固定污染源废气中NMHC与VOCs监测总烃毛细管柱HH-THC-30 详细信息:


名称:总烃毛细管柱

规格:30m*0.53mm

型号:HH-THC-30

应用:

HJ 604-2017环境空气 总烃、甲烷和非甲烷总烃的测定 直接进样-气相色谱法

HJ 38-2017固定污染源废气 总烃、甲烷和非甲烷总烃的测定 气相色谱法


浩瀚色谱(山东)应用技术开发有限公司结合固定污染源监测工作的实际情况,针对气相色谱法测定污染源废气中非甲烷总烃(NMHC)的影响因素进行探讨。研究发现:单标标气与混标标气标定同一样品时,浓度存在差异。采样方法、采样容器材质、体积对监测结果准确性的影响较为严重。为此,应更加严格规范固定污染源废气采样方法,增加固定污染源监测结果的准确性。同时通过对NMHC与VOCs的定义及现有方法进行比较,详细分析了两者关系及同等条件下数值差异,结果表明:不同行业,由于特征污染物的区别,两者有效碳质量浓度呈现的比例并不一致。此外,基于FID响应值的NMHC不能准确全面反映空气有机污染程度,可能会掩盖废气中某些有机污染。

NMHC and VOCs in fixed pollution source exhaust gas monitor total hydrocarbon capillary column HH-THC-30


The capillary column HH-THC-30 for total hydrocarbon monitoring of NMHC and VOCs in exhaust gas from stationary sources:




Name: Total Hydrocarbon Capillary Column


Specification: 30m*0.53mm


Model: HH-THC-30


application:


HJ 604-2017 Ambient air Determination of total hydrocarbons, methane and non-methane total hydrocarbons Direct sampling-gas chromatography


HJ 38-2017 Determination of Total Hydrocarbons, Methane and Non-Methane Total Hydrocarbons in Waste Gas from Stationary Pollution Sources Gas Chromatography




Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd., combined with the actual situation of fixed pollution source monitoring, discussed the influencing factors of non-methane total hydrocarbons (NMHC) in the exhaust gas of pollution sources by gas chromatography. The study found that there is a difference in concentration between single-standard gas and mixed-standard gas when calibrating the same sample. The sampling method, the material and volume of the sampling container have a serious impact on the accuracy of the monitoring results. For this reason, it is necessary to more strictly regulate the sampling method of fixed pollution sources and increase the accuracy of the monitoring results of fixed pollution sources. At the same time, by comparing the definitions of NMHC and VOCs and the existing methods, the relationship between the two and the numerical difference under the same conditions are analyzed in detail. Not inconsistent. In addition, the NMHC based on the FID response value cannot accurately and comprehensively reflect the degree of air organic pollution, and may cover up some organic pollution in the exhaust gas.
