填充柱气相色谱法测定大气废气中甲醇 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

目前测定空气中甲醇的方法主要有品红亚硫酸比色法和气相色谱法.比色法的灵敏度25μg/5ml,不能满足环境中甲醇测定的需要.

气相色谱法用纯水吸收空气中的甲醇,从该法的谱图可以看出与乙醇的分离不够理想,当空气中有大量的乙醇与甲醇共存时,对甲醇的分离将带来不利的影响.浩瀚色谱（山东）应用技术开发有限公司采用5%Carbowax 20M Carbopack B填充柱测定废气中甲醇，效率高，结果满意。

Determination of Methanol in Atmospheric Waste Gas by Packed Column Gas Chromatography
Determination of Methanol in Atmospheric Waste Gas by Packed Column 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



At present, the main methods for the determination of methanol in the air are the magenta sulfurous acid colorimetric method and the gas chromatography method. The sensitivity of the colorimetric method is 25μg/5ml, which cannot meet the needs of methanol determination in the environment.

Gas chromatography uses pure water to absorb methanol in the air. From the spectrum of this method, it can be seen that the separation from ethanol is not ideal. When a large amount of ethanol and methanol coexist in the air, the separation of methanol will be adversely affected. .Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used a 5% Carbowax 20M Carbopack B packed column to measure methanol in exhaust gas with high efficiency and satisfactory results.
