    应用: HJ T33-1999 固定污染源排气中甲醇的测定气相色谱法 
    浩瀚色谱(山东)应用技术开发有限公司采用纯水直接吸收,用A、B、二级吸收液富集高含量甲醇气样的总回收率为95.7%,变异系数%:低含量甲醇样品回收率大于90%,变异系数5%左右。用带FID的气相色谱仪进行分析,5%Carbowax 20M Carbopack B为固定相,甲醇与乙醇可以分开(R=1.21),以峰面积法定量,甲醇的*低检出浓度为0.2mg/m~3。


    HJ/T 33-1999 Determination of Methanol in Exhaust Gas from Stationary Pollution Sources Gas Chromatography
    This standard applies to the determination of methanol from fixed sources of organized emissions and unorganized emissions.

    Name: Packed column
    Chromatographic stationary liquid: 5% polyethylene glycol
    Carrier: Graphite carbon black 80-120 mesh

    Specification: 2m*3mm, 2m*1/8

    Model: 5% Carbowax 20M Carbopack B

    Application: HJ T33-1999 Determination of Methanol in Exhaust Gas from Stationary Pollution Sources Gas Chromatography

    Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses pure water to directly absorb, and the total recovery rate of enrichment of high-content methanol gas samples with A, B, and secondary absorption liquids is 95.7%, and the coefficient of variation%: the recovery rate of low-content methanol samples It is greater than 90%, and the coefficient of variation is about 5%. Analyze with a gas chromatograph with FID, 5% Carbowax 20M Carbopack B is the stationary phase, methanol and ethanol can be separated (R=1.21), quantified by the peak area method, the minimum detectable concentration of methanol is 0.2mg/m~3 .
