聚乙二醇-400填充柱”
以聚乙二醇-400（PEG-400）作为固定相，涂渍在惰性固体载体上，并填充在金属或玻璃管中制成的气相色谱柱。
核心组成部分
一个完整的聚乙二醇-400填充柱由三部分构成：
柱管：通常为不锈钢或玻璃材质，长度一般在1-3米，内径2-4毫米。
载体：一种化学惰性、多孔性的固体颗粒，作用是承载固定液。常用的有：
Chromosorb W：白色硅藻土载体，惰性好，适用于极性固定液和分析极性样品。
Chromosorb P：红色硅藻土载体，吸附性稍强。
玻璃微球：非硅藻土载体，吸附性极低。
固定相：聚乙二醇-400。
PEG-400 是一种平均分子量为400的聚乙二醇，在室温下为液体。
它是一种极性的固定相，其分离机理主要基于物质与固定相之间的氢键作用力和偶极-偶极相互作用。

浩瀚色谱研制的PEG400填充柱的主要特点：
极性：属于中强极性固定相。
“通用型”极性柱：因其良好的分离效果和适中的价格，在过去几十年中被广泛应用。
*高使用温度：相对较低，通常为70-120°C。这是因为PEG-400分子量较小，蒸气压较高，温度过高会导致固定液流失严重，基线不稳，柱寿命缩短。
应用范围：特别适用于分离极性化合物和可形成氢键的化合物。

 

Polyethylene glycol 400 packed column
A gas chromatography column made by coating PEG-400 as a stationary phase on an inert solid carrier and filling it in a metal or glass tube.
Core components
A complete polyethylene glycol-400 packed column consists of three parts:
Column tube: usually made of stainless steel or glass material, with a length of 1-3 meters and an inner diameter of 2-4 millimeters.
Carrier: A chemically inert, porous solid particle used to carry a fixative. Commonly used ones include:
Chromosorb W: a white diatomaceous earth carrier with good inertness, suitable for polar fixatives and analysis of polar samples.
Chromosorb P: a red diatomaceous earth carrier with slightly stronger adsorption properties.
Glass microspheres: Non diatomaceous earth carrier, with extremely low adsorption capacity.
Fixed phase: Polyethylene glycol-400.
PEG-400 is a polyethylene glycol with an average molecular weight of 400, which is liquid at room temperature.
It is a polar stationary phase, and its separation mechanism is mainly based on hydrogen bonding forces and dipole dipole interactions between the substance and the stationary phase.

The main features of the PEG400 packed column developed by Haohan Chromatography are:
Polarity: Belongs to the fixed phase of medium strong polarity.
Universal polarity column: Due to its excellent separation effect and moderate price, it has been widely used in the past few decades.
Maximum operating temperature: relatively low, usually 70-120 ° C. This is because PEG-400 has a small molecular weight and high vapor pressure. Excessive temperature can cause severe loss of fixative, unstable baseline, and shortened column life.
Application scope: Especially suitable for separating polar compounds and compounds that can form hydrogen bonds.
