總烴柱玻璃微球應用：非甲烷總烴分析


非甲烷烴(NMHC)通常是指除甲烷以外的所有可揮發的碳氫化合物(其中主要是C2~C8),又稱非甲烷總烴。大氣中的NMHC超過一定濃度,除直接對人體健康有害外,在一定條件下經日光照射還能產生光化學煙霧,對環境和人類造成危害。其測定方法主要分為熱解析法和直接進樣法,其中直接進樣。

滕州市浩瀚色譜儀器技術服務有限公司，采用《空氣和廢氣監測分析方法(第四版增補版)》P587~P589總烴和非甲烷總烴測定方法一(B)利用六通閥定量環進樣來測定環境空氣以及廢氣中的非甲烷總烴濃度,對儀器條件進行優化,方法的檢出限為0.13 mg/m3,標樣總烴相對標準偏差為0.4%,甲烷的相對標準偏差為1.2%,總烴的加標回收率為100.9~101.6%,甲烷的加標回收率為102.4~102.6%,該方法操作簡單,分析速度快,實驗結果滿意。

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.
