haohan毛细管柱PEG-20M应用在安捷伦7890B上30m*0.32mm*1um

PEG-20M毛细管柱是分析极性挥发性有机物，尤其是含氧化合物的首选利器。只要了解其极性强、怕酸碱、有温度上限的特性，并正确维护，它就能在食品、环境、化工等诸多领域提供稳定可靠的分离结果。
、 典型分离对象（化合物类别）
醇类：甲醇、乙醇、丙醇、丁醇等所有同系物和异构体。
酯类：乙酸乙酯、乳酸乙酯等各种脂肪酸酯。
醛类和酮类：甲醛、乙醛、丙酮、丁酮等。
脂肪酸：特别是短链（C2-C6）游离脂肪酸。
乙二醇类：乙二醇、丙二醇、丁二醇等。
酚类：苯酚、甲酚等。
胺类：某些低级胺（但分离碱性化合物时，峰易拖尾，常需使用碱性脱活柱或改用专用胺柱）。

浩瀚色谱（山东）应用技术开发有限公司,研制的《PEG20M毛细管色谱柱应用岛津GC2010》：应用示例（白酒分析）
这是PEG-20M柱*经典的应用之一。
目标物：白酒中几十种微量风味物质，如乙酸乙酯、乳酸乙酯、己酸乙酯、甲醇、异丁醇、异戊醇、乙酸、己酸等。

PEG-20M capillary column is the preferred tool for analyzing polar volatile organic compounds, especially oxygen-containing compounds. As long as we understand its strong polarity, acid and alkali resistance, and temperature limit characteristics, and maintain them correctly, it can provide stable and reliable separation results in many fields such as food, environment, and chemical industry.
Typical separation objects (compound categories)
Alcohols: all homologues and isomers of methanol, ethanol, propanol, butanol, etc.
Esters: various fatty acid esters such as ethyl acetate and ethyl lactate.
Aldehydes and ketones: formaldehyde, acetaldehyde, acetone, butanone, etc.
Fatty acids: especially short chain (C2-C6) free fatty acids.
Ethylene glycol: Ethylene glycol, propylene glycol, butanediol, etc.
Phenols: Phenol, cresol, etc.
Amines: Some lower amines (but when separating alkaline compounds, the peak is prone to tailing, often requiring the use of alkaline deactivation columns or specialized amine columns).
PEG20M Capillary Column Application Shimadzu GC2010 developed by Haohan Chromatography (Shandong) Application Technology Development Co., Ltd.: application example (Baijiu analysis)
This is one of the most classic applications of PEG-20M columns.
Target: dozens of trace flavor substances in Baijiu, such as ethyl acetate, ethyl lactate, ethyl hexanoate, methanol, isobutanol, isoamyl alcohol, acetic acid, caproic acid, etc.
Key points of the method:
Column temperature: Use programmed heating, such as starting from 50 ° C, increasing from 5-10 ° C/min to 220 ° C and maintaining for a period of time.
Injection method: Split injection is usually used to protect the chromatographic column.
Detector: Hydrogen flame ionization detector.
Sample pretreatment: direct injection or simple dilution.
