乙炔、乙烯、乙烷的色谱分离是气相色谱（GC）中的一个经典课题。这三种气体性质相似，但通过合理选择色谱柱和条件，可以实现高效分离。
分离难点
沸点接近：乙烷(-88.6°C)、乙烯(-103.7°C)、乙炔(-84°C)沸点都非常低，且相差不大，仅靠沸点差异（分配作用）分离效果不佳。
性质差异关键：它们的极性和不饱和度不同。
乙烷：非极性饱和烃。
乙烯：弱极性（π键），不饱和烯烃。
乙炔：线性分子，极性最强（碳碳三键），且酸性最强（氢原子略带酸性）

The chromatographic separation of acetylene, ethylene, and ethane is a classic topic in gas chromatography (GC). These three gases have similar properties, but efficient separation can be achieved through reasonable selection of chromatographic columns and conditions.
Difficulty in Separation
Boiling point proximity: Ethane (-88.6 ° C), ethylene (-103.7 ° C), and acetylene (-84 ° C) all have very low boiling points, and the difference is not significant. The separation effect is not good solely based on boiling point differences (distribution effect).
The key difference in properties is their polarity and unsaturation.
Ethane: non-polar saturated hydrocarbon.
Ethylene: weakly polar (π - bond), unsaturated olefin.
Acetylene: a linear molecule with the strongest polarity (carbon carbon triple bond) and the strongest acidity (hydrogen atom slightly acidic)
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a capillary chromatography column for the determination of ethylene, ethane, and acetylene using Shimadzu, which can clearly and completely separate ethane, ethylene, and acetylene, and perform accurate quantitative analysis.
