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。
浩瀚色谱（山东）应用技术开发有限公司，采用5%Carbowax20M Carbopack B填充柱建立了用纯水直接吸收环境空气或工业废气中的甲醇,采用顶空进样,气相色谱进行定性定量测定。该方法最低检出质量浓度为0.590mg·m^-3相对标准偏差在5%-7.2%之间,加标回收率在90%~121%之间。简单灵敏,线性范围良好,检出限低,精密度好,定性定量准确;经实际样品测定,完全满足环境空气和废气中甲醇的监测要求。

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.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a 5% Carbowax20M Carbopack B packed column to directly absorb methanol from ambient air or industrial waste gas using pure water. Headspace injection and gas chromatography are used for qualitative and quantitative determination. The minimum detectable concentration of this method is 0.590mg · m ^ -3, with a relative standard deviation between 5% and 7.2%, and a spiked recovery rate between 90% and 121%. Simple and sensitive, with a good linear range, low detection limit, good precision, and accurate qualitative and quantitative analysis; After actual sample testing, it fully meets the monitoring requirements for methanol in ambient air and exhaust gas.
