甲醇是重要的基礎(chǔ)化工原料和清潔燃料，在醫(yī)藥、農(nóng)藥、涂料、塑料、有機(jī)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(qiáng)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(jìn)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 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.
