2015年《環(huán)境狀況公報(bào)》顯示,大部分城市臭氧作為要污染物的天數(shù)有增加趨勢(shì)。而大氣中的VOCs是產(chǎn)生臭氧重要的前體物,同時(shí)也能對(duì)PM_(2.5)產(chǎn)生影響,成為監(jiān)測(cè)和控制的重點(diǎn),被納入總量控制體系。上海、廣州、西安等地方已采用非甲烷總烴作為VOCs的評(píng)價(jià)指標(biāo)。
滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，結(jié)合環(huán)境監(jiān)測(cè)分析工作的實(shí)際情況,探討了非甲烷總烴的樣品采集、進(jìn)樣方式、樣品色譜柱,結(jié)果表明:與注射器采樣相比,氣袋氣密性和化學(xué)惰性好,保存樣品時(shí)間長(zhǎng);采用一次進(jìn)樣,雙色譜柱GDX502/104、玻璃微球同時(shí)分離樣品,雙FID同時(shí)檢測(cè),節(jié)約時(shí)間,避免誤差,加快速、準(zhǔn)確。

Dedicated total hydrocarbon column for non-methane total hydrocarbon monitoring and analysis
Dedicated total hydrocarbon column for non-methane total hydrocarbon monitoring and analysis

According to the 2015 "State Bulletin of the State of the Environment of China", most cities have an increasing number of days with ozone as their primary pollutant. VOCs in the atmosphere are the most important precursors for ozone generation, and they can also affect PM_ (2.5). They have become the focus of monitoring and control, and have been included in the total amount control system. Shanghai, Guangzhou, Xi'an and other places have adopted non-methane total hydrocarbons as the evaluation index of VOCs.
Tengzhou Haohan Chromatographic Instrument Technology Service Co., Ltd., combined with the actual situation of environmental monitoring and analysis, discussed the sample collection, injection method and sample column of non-methane total hydrocarbons. Good inertness and chemical inertia, and long storage time of the sample; using one injection, dual chromatography column GDX502 / 104, glass microspheres to separate samples at the same time, dual FID detection at the same time, saving time, avoiding errors, faster and accurate.
