填充柱氣相色譜法測(cè)定大氣廢氣中甲醇
填充柱氣相色譜法測(cè)定大氣廢氣中甲醇 詳細(xì)信息：
目前測(cè)定空氣中甲醇的方法主要有品紅亞硫酸比色法和氣相色譜法.比色法的靈敏度25μg/5ml,不能滿(mǎn)足環(huán)境中甲醇測(cè)定的需要.
氣相色譜法用純水吸收空氣中的甲醇,從該法的譜圖可以看出與乙醇的分離不夠理想,當(dāng)空氣中有大量的乙醇與甲醇共存時(shí),對(duì)甲醇的分離將帶來(lái)不利的影響.浩瀚色譜（山東）應(yīng)用技術(shù)開(kāi)發(fā)有限公司采用5%Carbowax 20M Carbopack B填充柱測(cè)定廢氣中甲醇，效率高，結(jié)果滿(mǎn)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 statio
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.
