名稱(chēng)：填充柱
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.如要改善分離度,需加長(zhǎng)柱子,但水的出峰時(shí)間將長(zhǎng)達(dá)16分鐘以上,大大加長(zhǎng)了一個(gè)樣品的分析周期.
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，外標(biāo)法定量，結(jié)果準(zhǔn)確。

Improvement of Gas Chromatography Method for Determination of Methanol in Atmospheric Waste Gas
Improved method for determination of methanol in atmospheric exhaust gas by gas chromatography. 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. adopts 5% Carbowax 20M Carbopack B packed column, quantified by external standard method, and the results are accurate and reliable.
