Methanol is the simplest structured saturated monohydrate, usually produced by the reaction of carbon monoxide and hydrogen gas. Methanol can be mixed with water in any ratio, and industrial methanol is distilled to remove water.
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.
