With the development of modern industry, air pollution is also increasing. Methanol is one of the commonly used raw materials in the modern petrochemical industry. In the production process, it is inevitably released into the air. Methanol is a toxic, harmful, flammable and explosive substance. Non-methane total hydrocarbons (NMHC) generally refer to all volatile hydrocarbons other than methane. When the NMHC in the atmosphere exceeds a certain concentration, it directly damages the human health.

Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. uses a single inlet six-port valve injection, Porapak Q column and two empty packed columns and a FID detector for gas chromatography to determine methane, total hydrocarbons and unorganized atmosphere. Non-methane total hydrocarbons, the determination results are in line with the requirements of unorganized emission monitoring standards in the comprehensive emission standards for atmospheric pollutants. The minimum detectable concentrations were 0.04 mg/m3 for methane, 0.04 mg/m3 for total hydrocarbons, 0.06 mg/m3 for non-methane, and 2 mg/m3 for methanol, and maintained good repeatability. The relative standard deviations were less than 2%. , to meet the requirements of testing. The method is simple, sensitive and has good resolution, and has good reproducibility and reliable accuracy.
