浩瀚5%Carbowax20M Carbopack B，，80-120目，甲醇填充柱，，2m*3mm

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.

浩瀚色谱研制的5%Carbowax20M  Carbopack B不锈钢填充柱，甲醇不受乙醇，乙醛，丙酮的干扰，柱效高，分离好，定量准确可靠。

The main methods for determining methanol in the air include colorimetric method with red sulfite and gas chromatography The sensitivity of colorimetric method is 25 μ g/5ml, which cannot meet the needs of methanol determination in the environment The gas chromatography method uses pure water to absorb methanol from the air. From the spectrum of this method, it can be seen that the separation from ethanol is not ideal. When there is a large amount of ethanol coexisting with methanol in the air, it will have adverse effects on the separation of methanol To improve separation, the column needs to be lengthened, but the peak time of water will be more than 16 minutes, greatly extending the analysis cycle of a sample
The 5% Carbowax20M Carbopack B stainless steel packed column developed by Haohan Chromatography has high column efficiency, good separation, accurate and reliable quantification, and methanol is not affected by ethanol, acetaldehyde, and acetone.
