浩瀚HJ/T 33-1999固定污染源排气中甲醇的测定填充柱应用安捷伦，5%Carbowax20M Carbopack B5%Carbowax20M Carbopack B

使用 5% Carbowax 20M on Carbopack B 色谱柱配合GC-FID是测定废气中甲醇的可靠、灵敏且成熟的方法。成功的关键在于样品采集的代表性、有效的除水措施、优化的色谱分离条件以及严格的质量控制。

建议在建立方法时，参考相关的国家标准或行业指南（例如中国的《空气和废气监测分析方法》）进行验证。

高选择性：Carbowax 20M/Carbopack B组合对醇类等含氧化合物选择性好，能有效分离甲醇和常见的烃类物质。

高灵敏度：FID对甲醇的检测限很低，通常可达ppm甚至ppb级别，满足环境监测和 occupational health 标准的要求。

峰形好：惰性担体避免了极性分子的拖尾现象，峰形尖锐对称，有利于准确定量。

The use of 5% Carbowax 20M on Carbopack B chromatography column combined with GC-FID is a reliable, sensitive, and mature method for determining methanol in exhaust gas. The key to success lies in the representativeness of sample collection, effective water removal measures, optimized chromatographic separation conditions, and strict quality control.
It is recommended to refer to relevant national standards or industry guidelines (such as China's "Air and Waste Gas Monitoring and Analysis Methods") for validation when establishing methods.
High selectivity: The Carbowax 20M/Carbopack B combination has good selectivity for oxygen-containing compounds such as alcohols, and can effectively separate methanol and common hydrocarbon substances.
High sensitivity: FID has a very low detection limit for methanol, usually reaching ppm or even ppb levels, meeting the requirements of environmental monitoring and occupational health standards.
Good peak shape: The inert carrier avoids the tailing phenomenon of polar molecules, and the peak shape is sharp and symmetrical, which is conducive to accurate quantification.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed the Shimadzu Chromatographic Column for the determination of methanol in fixed pollution source exhaust gas. The column uses a gas chromatograph equipped with a hydrogen flame ionization detector for detection, with good separation, no interference, area external standard method, and accurate quantification of methanol.
