5% Carbowax 20M on Carbopack B 是一种特殊用途的填充色谱柱，是现代毛细管色谱技术的重要补充。它在环境监测（空气、废气、水质）中不可替代的作用是：精准分析那些在常规色谱柱上表现不佳的强极性挥发性有机物，特别是挥发性脂肪酸和酚类化合物。
载体 (Support): Carbopack B
一种高性能的石墨化炭黑。
特点：表面惰性极好，对极性化合物吸附性弱，无表面活性位点，因此能获得对称的色谱峰形，尤其适用于分析酸性、碱性等活性物质。
固定液 (Stationary Phase): Carbowax 20M
聚乙二醇 (PEG-20M)，是一种极性固定相。
特点：对含氧、含氮等极性化合物（如醇、醛、酮、酸、酯、酚）有很强的选择性保留和优异的分离能力。
组合优势：
这种“强极性固定液 + 惰性石墨化炭黑载体”的组合，使其成为分析挥发性脂肪酸（如甲酸、乙酸）、酚类（如苯酚） 等难以用常规毛细管柱分析的强极性物质的首选色谱柱。

5% Carbowax 20M on Carbopack B is a special purpose packed chromatography column that is an important supplement to modern capillary chromatography technology. Its irreplaceable role in environmental monitoring (air, exhaust gas, water quality) is to accurately analyze highly polar volatile organic compounds, especially volatile fatty acids and phenolic compounds, that perform poorly on conventional chromatographic columns.
Carrier (Support): Carbopack B
A high-performance graphitized carbon black.
Characteristics: Excellent surface inertness, weak adsorption of polar compounds, no surface active sites, thus able to obtain symmetrical chromatographic peak shapes, especially suitable for analyzing acidic, alkaline and other active substances.
Fixed phase: Carbowax 20M
Polyethylene glycol (PEG-20M) is a polar stationary phase.
Characteristics: It has strong selective retention and excellent separation ability for polar compounds such as alcohols, aldehydes, ketones, acids, esters, and phenols containing oxygen and nitrogen.
Combination advantage:
This combination of "strongly polar fixative+inert graphitized carbon black carrier" makes it the preferred chromatographic column for analyzing volatile fatty acids (such as formic acid, acetic acid), phenols (such as phenol), and other strongly polar substances that are difficult to analyze using conventional capillary columns.
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.
