非甲烷總烴作為揮發(fā)性有機物污染的重要指標,其監(jiān)測數(shù)據(jù)能直接反映VOCs污染的程度,對環(huán)境治理與管理均有重要意義。
浩瀚色譜（山東）應用技術開發(fā)有限公司采用氣袋法采樣,十通閥進樣,雙柱單FID氣相色譜法測定廢氣中非甲烷總烴的濃度,通過對監(jiān)測全過程的不確定度評定,找出對監(jiān)測結果準確度影響最大的因素為校準曲線的擬合,并針對性地提出提高監(jiān)測結果準確度的改進方法。

As an important indicator of volatile organic compound pollution, non methane total hydrocarbons can directly reflect the degree of VOCs pollution through monitoring data, which is of great significance for environmental governance and management.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses gas bag sampling, ten way valve injection, and dual column single FID gas chromatography to determine the concentration of non methane total hydrocarbons in waste gas. Through evaluating the uncertainty of the entire monitoring process, it is found that the most influential factor on the accuracy of monitoring results is the fitting of calibration curves, and targeted improvement methods are proposed to improve the accuracy of monitoring results.
