非甲烷總烴(non-methane total hydrocarbons, NMHCs)作為揮發(fā)性有機(jī)物(volatile organic compounds, VOCs)的重要組成部分,具有強(qiáng)烈的光化學(xué)活性,在一定程度上可以反映城市環(huán)境空氣VOCs的總體污染情況。

 

浩瀚色譜(山東)應(yīng)用技術(shù)開(kāi)發(fā)有限公司采用采樣袋采樣,利用雙不銹鋼填充柱單FID檢測(cè)器直接進(jìn)樣氣相色譜法測(cè)定固定污染源廢氣中非甲烷總烴。結(jié)果表明:在試驗(yàn)條件下,低濃度或高濃度甲烷、總烴校準(zhǔn)曲線的相關(guān)系數(shù)均達(dá)到0.9996以上,當(dāng)進(jìn)樣量為1.0 mL時(shí),甲烷的檢出限(以甲烷計(jì))為0.053 mg/m3,總烴的檢出限(以甲烷計(jì))為0.056 mg/m3。甲烷的相對(duì)標(biāo)準(zhǔn)偏差在1.32%~1.91%之間,相對(duì)誤差在-3.77%~7.00%之間;總烴的相對(duì)標(biāo)準(zhǔn)偏差在0.92%~4.05%之間,相對(duì)誤差在-8.11%~6.69%之間。該方法操作簡(jiǎn)單,準(zhǔn)確度高,可滿(mǎn)足固定污染源廢氣中非甲烷總烴的測(cè)定。

Non methane total hydrocarbons (NMHCs), as an important component of volatile organic compounds (VOCs), have strong photochemical activity and can to some extent reflect the overall pollution of urban ambient air VOCs.
 
 
 
 
 
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses sampling bags for sampling, and uses a dual stainless steel packed column single FID detector to directly inject gas chromatography to determine non methane total hydrocarbons in fixed pollution source exhaust gas. The results showed that under experimental conditions, the correlation coefficients of the calibration curves for low or high concentrations of methane and total hydrocarbons reached above 0.9996. When the injection volume was 1.0 mL, the detection limit of methane (measured by methane) was 0.053 mg/m3, and the detection limit of total hydrocarbons (measured by methane) was 0.056 mg/m3. The relative standard deviation of methane is between 1.32% and 1.91%, and the relative error is between -3.77% and 7.00%; The relative standard deviation of total hydrocarbons is between 0.92% and 4.05%, and the relative error is between -8.11% and 6.69%. This method is simple to operate and has high accuracy, and can meet the determination of non methane total hydrocarbons in fixed pollution source exhaust gas.
