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. ?
