“硫酸钠去活的氧化铝色谱柱”是一种体现经典色谱智慧的技术，在需要对吸附剂活性进行精细调控时，它仍然具有实用价值。如果您正在进行特定化合物的分离，且发现在硅胶或普通氧化铝上效果不佳，可以考虑尝试这种方法。

“去活”的含义：对于许多化合物，特别是对酸、碱敏感或极性较强的物质，使用高活性的氧化铝会导致吸附过强、样品分解、拖尾严重、回收率低等问题。“去活”就是通过人为添加特定物质（这里是硫酸钠），来有控制地、稳定地降低其表面活性，使其更适合分离。

优点：
活性稳定可控，重复性好。
减少样品分解和不可逆吸附。
改善峰形，提高分离效率。

Sodium sulfate deactivated alumina chromatography column "is a technique that embodies classical chromatographic wisdom, and it still has practical value when precise regulation of adsorbent activity is required. If you are conducting the separation of a specific compound and find that it does not perform well on silica gel or ordinary alumina, you may consider trying this method.
The meaning of "deactivation": For many compounds, especially those that are sensitive to acids, bases, or have strong polarity, using highly active alumina can lead to problems such as strong adsorption, sample decomposition, severe tailing, and low recovery rate. 'Deactivation' refers to the controlled and stable reduction of surface activity by artificially adding specific substances (here sodium sulfate) to make them more suitable for separation.
Advantages:
Stable and controllable activity, good repeatability.
Reduce sample decomposition and irreversible adsorption.
Improve peak shape and enhance separation efficiency.

Linear and quantitative analysis of polar unsaturated hydrocarbons.
The chromatographic column is renewable and can restore its full efficacy and selectivity after adsorbing water.
Strict testing ensures that the film thickness (1,3-butadiene), selectivity (propadiene, methylacetylene), resolution (trans-2-butene, 1-butene), and coating efficiency (1,3-butadiene) are all in place.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed and produced the "Sodium Sulfate Activated Alumina Chromatography Column Application Agilent", which has high column efficiency and good separation of methane, ethane, ethylene, propane, propylene, butane, and pentane. It has been installed and used on Agilent, Shimadzu, Thermo Fisher, Varian, Brooke, and PE with good results.
