408有機(jī)擔(dān)體是一種在氣相色譜（GC）中非常經(jīng)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、耐高溫、極性弱等特點(diǎn)，特別適用于分析揮發(fā)性有機(jī)物（VOCs）、永久氣體和低分子量極性化合物。
由于其性能與國(guó)際上知名的Porapak系列（如Porapak Q）?和Hayesep系列填料非常相似，因此在很多應(yīng)用中可以互換或作為替代品。

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 ? 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 ?, 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.
