作為揮發性有機物總體排放情況表征的重要因子之一,非甲烷總烴的監測數據質量具有重要意義。
當非甲烷總烴的廢氣樣品中組分復雜時,浩瀚色譜（山東）應用技術開發有限公選用1m的總烴柱改善總烴柱上總烴峰型分叉、拖尾等現象,升高柱溫后,甲烷柱上氧峰和甲烷峰能夠分離;采樣容器選用氣袋更佳,每批氣袋使用前必須做好驗收,以保證氣袋本底對樣品無明顯影響;保證總烴柱徹底硅烷化、進樣閥不受污染,凈化載氣,盡可能地減少對試驗結果的干擾,保證非甲烷總烴結果的準確。

As one of the important factors characterizing the overall emission of volatile organic compounds, the quality of monitoring data for non methane total hydrocarbons is of great significance.
When the components in the exhaust gas sample of non methane total hydrocarbons are complex, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses a 1m total hydrocarbon column to improve the phenomenon of total hydrocarbon peak branching and tailing on the total hydrocarbon column. After raising the column temperature, the oxygen peak and methane peak on the methane column can be separated; It is better to use air bags as sampling containers, and each batch of air bags must be inspected before use to ensure that the background of the air bags has no significant impact on the samples; Ensure complete silanization of the total hydrocarbon column, prevent contamination of the injection valve, purify the carrier gas, minimize interference with the test results, and ensure the accuracy of non methane total hydrocarbon results.
