2015年《环境状况公报》显示,大部分城市臭氧作为要污染物的天数有增加趋势。而大气中的VOCs是产生臭氧重要的前体物,同时也能对PM_(2.5)产生影响,成为监测和控制的重点,被纳入总量控制体系。上海、广州、西安等地方已采用非甲烷总烃作为VOCs的评价指标。
滕州市浩瀚色谱仪器技术服务有限公司，结合环境监测分析工作的实际情况,探讨了非甲烷总烃的样品采集、进样方式、样品色谱柱,结果表明:与注射器采样相比,气袋气密性和化学惰性好,保存样品时间长;采用一次进样,双色谱柱GDX502/104、玻璃微球同时分离样品,双FID同时检测,节约时间,避免误差,加快速、准确。

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.


Stationary phase: silanized glass microspheres

Granularity: 60-80 mesh

Specification: 2m * 3mm

Model: HH-THC-2

High column efficiency and good separation
