空气中甲醇短时间浓度的检测填充柱
空气中甲醇短时间浓度的检测填充柱 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纯水低温吸收空气中甲醇、常温吹脱捕集-热解析对试样进行前处理浓缩甲醇的分析方法。采用气相色谱法氢焰离子化检测,提高了方法的灵敏度,降低了方法的检出限。当采样体积为3L时,低检出浓度为0.08mg/m3,分析的相对标准偏差为0.63%-4.60%,回收率99.3%-105.0%。能够满足安全生产、环境保护以及职业健康监护的要求。

Packed column for detecting the short-time concentration of methanol in the air
Packed column for detecting the concentration of methanol in the air for a short time. 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) Application Technology Development Co., Ltd. has established an analysis method for pure water to absorb methanol in the air at low temperature, and to pre-treat the sample and concentrate the methanol. The use of gas chromatography hydrogen flame ionization detection improves the sensitivity of the method and reduces the detection limit of the method. When the sampling volume is 3L, the lowest detection concentration is 0.08mg/m3, the relative standard deviation of the analysis is 0.63%-4.60%, and the recovery rate is 99.3%-105.0%. It can meet the requirements of safe production, environmental protection and occupational health monitoring.
