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。

The 2015 China Environmental Status Bulletin shows that the number of days of ozone as the primary pollutant in most cities has increased. The VOCs in the atmosphere are the most important precursors for the production of ozone. They also have an impact on PM_(2.5) and become the focus of monitoring and control. They are included in the total control system. Non-methane total hydrocarbons have been used as indicators for the evaluation of VOCs in Shanghai, Guangzhou, and Xi'an.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd., combined with the actual situation of environmental monitoring and analysis, explored the sample collection, injection mode and sample column of non-methane total hydrocarbons. The results show that the air bag is airtight compared with the syringe sampling. Sexual and chemical inertness is good, and the sample storage time is long; with one injection, the double column GDX502/104 and the glass microsphere simultaneously separate the sample, and the double FID is simultaneously detected, saving time, avoiding errors, and being more rapid and accurate.
