The structure and properties of Al_2O_3 after high temperature calcination and alkali metal chlorination deactivation have changed greatly. When it is used as a chromatographic stationary phase to make a 2m×φ2mm packed column to analyze gaseous hydrocarbon compounds and polymer-grade propylene, it shows the dual advantages of packed column and capillary column, and has the characteristics of fast response, high separation efficiency and low detection limit. .

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. discussed the deactivation mechanism of Al_2O_3 and the influence of processing conditions on analytical performance, and the different effects of Al_2O_3 on chromatographic separation due to the difference in preparation methods and existing forms.
