5%Carbowax 20M Carbopack B填充柱 气相色谱法测定大气废气中甲醇的详细介绍
气相色谱法测定大气废气中甲醇
气相色谱法测定大气废气中甲醇 详细信息：
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.如要改善分离度,需加长柱子,但水的出峰时间将长达16分钟以上,大大加长了一个样品的分析周期.
浩瀚色谱（山东）应用技术开发有限公司采用5%Carbowax 20M Carbopack B色谱柱 分析大气废气中甲醇，效率高，效果满意。

Determination of Methanol in Air Waste Gas by Gas Chromatography
Gas Chromatography Determination of Methanol in Atmospheric Waste Gas Details:
Name: Packed column
Chromatographic statio
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 Statio
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. , It can be seen from the spectrum of this method that the separation with ethanol is not ideal. When a large amount of ethanol and methanol coexist in the air, it will have an adverse effect on the separation of methanol. If you want to improve the resolution, you need to lengthen the column. However, the peak time of water will be as long as 16 minutes, which greatly lengthens the analysis period of a sample.
Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses a 5% Carbowax 20M Carbopack B chromatographic column to analyze methanol in atmospheric exhaust gas with high efficiency and satisfactory results.
