408有机担体是一种在气相色谱（GC）中非常经典的多孔聚合物固定相，由苯乙烯和二乙烯基苯共聚而成。它具有疏水性、耐高温、极性弱等特点，特别适用于分析挥发性有机物（VOCs）、永久气体和低分子量极性化合物。
由于其性能与国际上知名的Porapak系列（如Porapak Q） 和Hayesep系列填料非常相似，因此在很多应用中可以互换或作为替代品。
特性描述主要优点疏水性强（不惧水样）、对极性化合物峰形好、耐高温（通常可达250℃）、对CO₂和轻烃分离效果好常用规格内径2-3 mm，长度1-3米，80-100目，不锈钢或玻璃材质主要应用永久气体、CO₂、C1-C3轻烃、挥发性有机物（VOCs）、醇类、醛类、水分等注意事项1. 老化：新柱或长时间未使用的柱子需要在最高使用温度下（低于250℃）通载气老化数小时，以去除残留杂质和水分。
2. 样品：避免注入高沸点或不易挥发的物质，以免污染固定相，导致柱效下降。
3. 替代品可与Porapak Q、Hayesep Q/N等系列柱子互为替代，但具体方法可能需要微调。

408 organic support is a very classic porous polymer stationary phase in gas chromatography (GC), which is copolymerized from styrene and divinylbenzene. It has the characteristics of hydrophobicity, high temperature resistance, and weak polarity, making it particularly suitable for analyzing volatile organic compounds (VOCs), permanent gases, and low molecular weight polar compounds.
Due to its performance being very similar to internationally renowned Porapak series (such as Porapak Q) and Hayesep series fillers, it can be interchangeable or used as a substitute in many applications.
Main advantages of characteristic description: strong hydrophobicity (not afraid of water samples), good peak shape for polar compounds, high temperature resistance (usually up to 250 ℃), good separation effect for CO ₂ and light hydrocarbons. Common specifications include inner diameter of 2-3 mm, length of 1-3 meters, 80-100 mesh. Stainless steel or glass materials are mainly used for permanent gases, CO ₂, C1~3 light hydrocarbons, volatile organic compounds (VOCs), alcohols, aldehydes, moisture, etc. Precautions: 1. Aging: New columns or columns that have not been used for a long time need to be aged with gas for several hours at the highest operating temperature (below 250 ℃) to remove residual impurities and moisture.
2. Sample: Avoid injecting high boiling or non-volatile substances to prevent contamination of the stationary phase and reduce column efficiency.
3. Substitutes can be used to replace Porapak Q, Hayesep Q/N and other series of columns, but the specific method may need to be fine tuned.
