Methanol is an important basic chemical raw material and clean fuel, widely used in industries such as pharmaceuticals, pesticides, coatings, plastics, and organic synthetic chemicals. Methanol has strong toxicity to the human body, low boiling point, and is easily volatile into the air. It is listed as one of the gaseous pollutants in environmental air and fixed source exhaust gas.
This standard is applicable to the determination of methanol in both organized and unorganized emissions from fixed pollution sources. When the chromatographic peak height is calculated at 3 times the noise, the detection limit of the method is 2mg/m3 when the chromatographic injection volume is 1.0ml; The concentration range for quantitative determination is 5.0~104mg/m3.
