低碳烃(C1～C5)不仅可以作为燃料使用，而且还是重要的有机合成基本原料。但是低碳烃的沸点很低，且有的组分沸点相差太小，这给分析造成了很大的困难。Al2O3 柱对低沸点化合物有较强的保留能力。

浩瀚色谱（山东）应用技术开发有限公司研发氧化铝填充柱对常用石油液化气、高C4含量石油液化气、聚合级烯烃和石油液化气中二甲醚进行了检测。具有较好的柱惰性、良好的选择性和较高的柱容量;其对C1～C5低碳烃具有较好的分离作用，能够基线分离所有组分，特别是难分离物质对丁烯异构体分离度均能达2.0以上，有助于各组分的综合利用;适用于高C4含量液化气、石油液化气中二甲醚以及聚合级乙烯、丙烯的分析，对工业上丁烯异构体的提取和利用以及聚合级烯烃的生产具有指导意义。

Low-carbon hydrocarbons (C1～C5) can not only be used as fuels, but also important basic raw materials for organic synthesis. However, the boiling point of low-carbon hydrocarbons is very low, and the boiling point difference of some components is too small, which makes the analysis very difficult. The Al2O3 column has a strong retention capacity for low boiling point compounds.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed alumina packed columns to detect the dimethyl ether in commonly used petroleum liquefied petroleum gas, high C4 content petroleum liquefied petroleum gas, polymer grade olefins and petroleum liquefied petroleum gas. It has good column inertness, good selectivity and high column capacity; it has a good separation effect on C1～C5 low-carbon hydrocarbons, and can baseline separation of all components, especially the difficult-to-separate substances for butene isomerization The separation degree can reach more than 2.0, which is helpful to the comprehensive utilization of each component; it is suitable for the analysis of high C4 content liquefied petroleum gas, dimethyl ether in petroleum liquefied petroleum gas, and polymer grade ethylene and propylene. The extraction and utilization of organic compounds and the production of polymer-grade olefins are of guiding significance.
