作为挥发性有机物总体排放情况表征的重要因子之一,非甲烷总烃的监测数据质量具有重要意义。

　　当非甲烷总烃的废气样品中组分复杂时,浩瀚色谱（山东）应用技术开发有限公选用1m的总烃柱改善总烃柱上总烃峰型分叉、拖尾等现象,升高柱温后,甲烷柱上氧峰和甲烷峰能够分离;采样容器选用气袋更佳,每批气袋使用前必须做好验收,以保证气袋本底对样品无明显影响;保证总烃柱彻底硅烷化、进样阀不受污染,净化载气,尽可能地减少对试验结果的干扰,保证非甲烷总烃结果的准确。

　　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.
