5% Carbowax 20M on Carbopack B 是一種特殊用途的填充色譜柱，是現(xiàn)代毛細管色譜技術(shù)的重要補充。它在環(huán)境監(jiān)測（空氣、廢氣、水質(zhì)）中不可替代的作用是：精準分析那些在常規(guī)色譜柱上表現(xiàn)不佳的強極性揮發(fā)性有機物，特別是揮發(fā)性脂肪酸和酚類化合物。
?
載體 (Support): Carbopack B
一種高性能的石墨化炭黑。
特點：表面惰性極好，對極性化合物吸附性弱，無表面活性位點，因此能獲得對稱的色譜峰形，尤其適用于分析酸性、堿性等活性物質(zhì)。
固定液 (Stationary Phase): Carbowax 20M
聚乙二醇 (PEG-20M)，是一種極性固定相。
特點：對含氧、含氮等極性化合物（如醇、醛、酮、酸、酯、酚）有很強的選擇性保留和優(yōu)異的分離能力。
組合優(yōu)勢：
這種“強極性固定液 + 惰性石墨化炭黑載體”的組合，使其成為分析揮發(fā)性脂肪酸（如甲酸、乙酸）、酚類（如苯酚） 等難以用常規(guī)毛細管柱分析的強極性物質(zhì)的首選色譜柱。

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.
