甲醇主要用于精细化工，塑料等领域，可用来制造甲醛、醋酸等多种有机产品，也是农药和医药的重要原料之一。甲醇在深加工后可作为一种新型清洁燃料，也加入汽油混合使用。甲醇在医药、农药、涂料、塑料、有机合成化工等行业领域有广泛应用。甲醇对人体具有强烈毒性，沸点较低，易挥发到空气中，被列为环境空气和固定污染源废气的气态污染物之一。
本标准适用于固定污染源有组织排放和无组织排放的甲醇测定。以3倍噪音色谱峰高值计算，当色谱进样量为1.0ml时，方法的检出限为2mg/m3；定量测定的浓度范围为5.0～104mg/m3。

Methanol is mainly used in fine chemicals, plastics and other fields, and can be used to manufacture various organic products such as formaldehyde and acetic acid. It is also an important raw material for pesticides and pharmaceuticals. Methanol can be used as a new type of clean fuel after deep processing, and can also be mixed with gasoline for use. Methanol is widely used in industries such as pharmaceuticals, pesticides, coatings, plastics, and organic synthesis chemicals. Methanol has strong toxicity to the human body, a low boiling point, and is easily volatile into the air, and is listed as one of the gaseous pollutants in ambient air and fixed source exhaust gases.
This standard is applicable to the determination of methanol in organized and unorganized emissions from fixed pollution sources. The detection limit of the method is 2mg/m3 when the chromatographic injection volume is 1.0ml, calculated based on the peak height of the 3-fold noise chromatography; The concentration range for quantitative determination is 5.0-104mg/m3.
