氣相色譜測定大氣廢氣中甲醇 詳細信息：

名稱：填充柱

色譜固定液：5%聚乙二醇
載體：石墨炭黑80-120目

規(guī)格：2m*3mm，2m*1/8

型號：5%Carbowax 20M Carbopack B

應用： HJ T33-1999 固定污染源排氣中甲醇的測定氣相色譜法 

目前測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,不能滿足環(huán)境中甲醇測定的需要.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,當空氣中有大量的乙醇與甲醇共存時,對甲醇的分離將帶來不利的影響.


浩瀚色譜（山東）應用技術開發(fā)有限公司采用5%Carbowax 20M Carbopack B填充柱，面積外標法定量，結果滿意。

Determination of Methanol in Atmospheric Waste Gas by Gas Chromatography
Gas Chromatography Determination of Methanol in Atmospheric Waste Gas Details:

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 from Stationary Pollution Sources Gas Chromatography



The current methods for determining methanol in the air mainly include fuchsin sulfurous acid colorimetry and gas chromatography. 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 with ethanol is not ideal.When a large amount of ethanol and methanol coexist in the air, the separation of methanol will have an adverse effect.


Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses 5% Carbowax 20M Carbopack B packed column, and the area external standard method is used for quantification, with satisfactory results.
