空气、废气中甲醇的气相色谱法测定 详细信息：

名称：填充柱

色谱固定液：5%聚乙二醇
载体：石墨炭黑80-120目

规格：2m*3mm，2m*1/8

型号：5%Carbowax 20M Carbopack B

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,PEG—6000为固定相,国产101白色担体,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。

Determination of methanol in air and waste gas by gas chromatography
Determination of methanol in air and waste gas by gas chromatography Details:

Name: Packed Column

Chromatographic fixative: 5% polyethylene glycol
Carrier: graphite carbon black 80-120 mesh

Specifications: 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 by gas chromatography



Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used pure water to directly absorb, and the total recovery rate of high-content methanol gas samples enriched with A, B, and secondary absorption liquids was 95.7%, and the coefficient of variation%: the recovery rate of low-content methanol samples More than 90%, the coefficient of variation is about 5%. The gas chromatograph with FID is used for analysis, PEG-6000 is the stationary phase, domestic 101 white support, methanol and ethanol can be separated (R=1.21), and the peak area method is used for quantification. The minimum detectable concentration of methanol is 0.2 mg/m ~3.
