总烃柱玻璃微球应用：非甲烷总烃分析


非甲烷烃(NMHC)通常是指除甲烷以外的所有可挥发的碳氢化合物(其中主要是C2~C8),又称非甲烷总烃。大气中的NMHC超过一定浓度,除直接对人体健康有害外,在一定条件下经日光照射还能产生光化学烟雾,对环境和人类造成危害。其测定方法主要分为热解析法和直接进样法,其中直接进样。

滕州市浩瀚色谱仪器技术服务有限公司，采用《空气和废气监测分析方法(第四版增补版)》P587~P589总烃和非甲烷总烃测定方法一(B)利用六通阀定量环进样来测定环境空气以及废气中的非甲烷总烃浓度,对仪器条件进行优化,方法的检出限为0.13 mg/m3,标样总烃相对标准偏差为0.4%,甲烷的相对标准偏差为1.2%,总烃的加标回收率为100.9~101.6%,甲烷的加标回收率为102.4~102.6%,该方法操作简单,分析速度快,实验结果满意。

Total Hydrocarbon Column Glass Microspheres

Details of total hydrocarbon column glass microspheres:

Specification: 1m*1/8; 1m*3mm

Granularity: 60-80 mesh

Application of total hydrocarbon column glass microspheres: non-methane total hydrocarbon analysis


Non-methane hydrocarbons (NMHC) usually refer to all volatile hydrocarbons except methane (mainly C2~C8), also known as non-methane total hydrocarbons. Exceeding a certain concentration of NMHC in the atmosphere, in addition to being directly harmful to human health, it can also produce photochemical smog under certain conditions under certain conditions, causing harm to the environment and humans. The determination method is mainly divided into thermal analysis method and direct sample injection method, among which direct sample injection.

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. adopts "Air and Waste Gas Monitoring and Analysis Methods (Fourth Edition Supplementary Edition)" P587~P589 Total Hydrocarbons and Non-Methane Total Hydrocarbons Determination Method One (B) Sampling using six-port valve To determine the concentration of non-methane total hydrocarbons in ambient air and exhaust gas, and optimize the instrument conditions, the detection limit of the method is 0.13 mg/m3, the relative standard deviation of standard total hydrocarbons is 0.4%, and the relative standard deviation of methane is 1.2% The standard addition recovery rate of total hydrocarbons is 100.9~101.6%, and the standard addition recovery rate of methane is 102.4~102.6%. The method is simple to operate, fast in analysis, and the experimental results are satisfactory.
