5%Carbowax 20M Carbopack B填充柱 详细信息：

名称：填充柱

色谱固定液：5%聚乙二醇
载体：石墨炭黑80-120目

规格：2m*3mm，2m*1/8

型号：5%Carbowax 20M Carbopack B

应用： HJ T33-1999 固定污染源排气中甲醇的测定气相色谱法 

浩瀚色谱（山东）应用技术开发有限公司建立了用纯水直接吸收环境空气或工业废气中的甲醇,采用顶空进样,气相色谱进行定性定量测定。该方法低检出质量浓度为0.500mg·m-3,相对标准偏差在4%~6.2%之间,加标回收率在88%~111%之间。结果表明,方法简单灵敏,线性范围良好,检出限低,精密度好,定性定量准确;经实际样品测定,完全满足环境空气和废气中甲醇的监测要求。

5%Carbowax 20M Carbopack B packed column 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

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. established the use of pure water to directly absorb methanol in ambient air or industrial waste gas, headspace sampling, and gas chromatography for qualitative and quantitative determination. The lowest detected mass concentration of this method is 0.500mg·m-3, the relative standard deviation is between 4% and 6.2%, and the recovery rate of standard addition is between 88% and 111%. The results show that the method is simple and sensitive, with good linear range, low detection limit, good precision, qualitative and quantitative accuracy; the actual sample determination fully meets the requirements for monitoring methanol in ambient air and exhaust gas.
