氣相色譜測(cè)定大氣廢氣中甲醇
氣相色譜測(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)甲醇的分離將帶來不利的影響.

Determination of Methanol in Atmospheric 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. 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.
