非甲烷总烃(non-methane total hydrocarbons, NMHCs)作为挥发性有机物(volatile organic compounds, VOCs)的重要组成部分,具有强烈的光化学活性,在一定程度上可以反映城市环境空气VOCs的总体污染情况。
浩瀚色谱(山东)应用技术开发有限公司采用采样袋采样,利用双不锈钢填充柱单FID检测器直接进样气相色谱法测定固定污染源废气中非甲烷总烃。结果表明:在试验条件下,低浓度或高浓度甲烷、总烃校准曲线的相关系数均达到0.9996以上,当进样量为1.0 mL时,甲烷的检出限(以甲烷计)为0.053 mg/m3,总烃的检出限(以甲烷计)为0.056 mg/m3。甲烷的相对标准偏差在1.32%~1.91%之间,相对误差在-3.77%~7.00%之间;总烃的相对标准偏差在0.92%~4.05%之间,相对误差在-8.11%~6.69%之间。该方法操作简单,准确度高,可满足固定污染源废气中非甲烷总烃的测定。

Non methane total hydrocarbons (NMHCs), as an important component of volatile organic compounds (VOCs), have strong photochemical activity and can to some extent reflect the overall pollution of urban ambient air VOCs.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses sampling bags for sampling, and uses a dual stainless steel packed column single FID detector to directly inject gas chromatography to determine non methane total hydrocarbons in fixed pollution source exhaust gas. The results showed that under experimental conditions, the correlation coefficients of the calibration curves for low or high concentrations of methane and total hydrocarbons reached above 0.9996. When the injection volume was 1.0 mL, the detection limit of methane (measured by methane) was 0.053 mg/m3, and the detection limit of total hydrocarbons (measured by methane) was 0.056 mg/m3. The relative standard deviation of methane is between 1.32% and 1.91%, and the relative error is between -3.77% and 7.00%; The relative standard deviation of total hydrocarbons is between 0.92% and 4.05%, and the relative error is between -8.11% and 6.69%. This method is simple to operate and has high accuracy, and can meet the determination of non methane total hydrocarbons in fixed pollution source exhaust gas.
