甲醇主要用于精細化工，塑料等領(lǐng)域，可用來制造甲醛、醋酸等多種有機產(chǎn)品，也是農(nóng)藥和醫(yī)藥的重要原料之一。甲醇在深加工后可作為一種新型清潔燃料，也加入汽油混合使用。甲醇在醫(yī)藥、農(nóng)藥、涂料、塑料、有機合成化工等行業(yè)領(lǐng)域有廣泛應(yīng)用。甲醇對人體具有強烈毒性，沸點較低，易揮發(fā)到空氣中，被列為環(huán)境空氣和固定污染源廢氣的氣態(tài)污染物之一。
?
本標(biāo)準(zhǔn)適用于固定污染源有組織排放和無組織排放的甲醇測定。以3倍噪音色譜峰高值計算，當(dāng)色譜進樣量為1.0ml時，方法的檢出限為2mg/m3；定量測定的濃度范圍為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.
