非甲烷總烴(NMHC)是除甲烷以外所有碳氫化合物的總和,具有較高光化學(xué)活性,是大氣污染防控的重要對象。其來源廣泛,包括工業(yè)排放、汽車尾氣等,可通過氣相色譜法等方法檢測,需通過廢氣治理、清潔能源推廣等手段控制。

Non methane total hydrocarbons (NMHC) are the sum of all hydrocarbons except methane, with high photocatalytic activity, and are important targets for air pollution prevention and control. It has a wide range of sources, including industrial emissions, automobile exhaust, etc. It can be detected by gas chromatography and other methods, and needs to be controlled through waste gas treatment, clean energy promotion, and other means.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a method for simultaneous determination of total hydrocarbons and non methane total hydrocarbons in ambient air using gas chromatography with a dual column dual hydrogen flame ionization detector (FID). The total hydrocarbon and methane content in the samples collected at the sampling point were determined, and the calculated mass concentration of non methane total hydrocarbons was less than 1.0mg · m-3. Using these two samples as matrices for spiked recovery experiments, the recovery rates of total hydrocarbons and methane were 103% to 106% and 108% to 110%, respectively; The relative standard deviations (n=5) of the measured values are 1.18% to 1.79% and 1.99% to 2.05%, respectively. ?
