安捷伦固体污染源排气中甲醇的测定填充柱5%Carbowax 20M Carbopack B

对于环境空气有毒物质测定中，固体污染源排气中甲醇的检测方法一般是采用气相色谱法，国家标准要求固体污染源排气中甲醇的测定调件为2m×2～3mm玻璃(或不锈钢)填充柱，色谱柱填充物：5％carbowax20mcarbopackb80～120目,柱温:70度；汽化室温度:200度；检测室温度:230度；载气(氮气)流量：32ml/min。
同样的，对于其他类环境空气有毒物质的测定中也可以采用气相色谱法，其核心技术是选择使用合适的色谱柱及合适的柱温、汽化室温度、检测室温度及载气流量。如果摸索不到合适的条件，将不会出峰或出峰不完全从而影响检测数据的准确性。

For the determination of toxic substances in the ambient air, gas chromatography is generally used for the detection of methanol in the exhaust of solid pollution sources. National standards require that the determination of methanol in the exhaust of solid pollution sources is a 2m×2～3mm glass (or stainless steel) packed column. , Chromatographic column packing: 5% carbowax20mcarbopackb 80～120 mesh, column temperature: 70 degrees; vaporization chamber temperature: 200 degrees; detection chamber temperature: 230 degrees; carrier gas (nitrogen) flow rate: 32ml/min.
Similarly, gas chromatography can also be used in the determination of other types of environmental air toxic substances. Its core technology is to select and use the appropriate chromatographic column and the appropriate column temperature, vaporization chamber temperature, detection chamber temperature and carrier gas flow. If the proper conditions are not found, there will be no peaks or incomplete peaks, which will affect the accuracy of the detection data.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd., developed a 5% polyethylene glycol/graphitized carbon black packed column 5% carbowax20mcarbopackb 80～120 mesh, with high column efficiency and good separation, which can meet the determination of methanol in fixed pollution source waste gas. The calibrated quantity has been used well on Agilent gas chromatographs and has been well received by customers.
