Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed a modified preparation method of γ?alumina microspheres. The precursor sol is prepared by using aluminum sec-butoxide as the aluminum source. The process is simple and fast. The prepared γ-alumina microspheres have high purity, which ensures the uniformity, sphericity, surface smoothness and strength of the microspheres; In the ring-shaped microchannel, the shear force generated by the co
ntinuous phase flow is used to obtain the dispersed phase droplets with high monodispersity. Furthermore, in the curing process, temperature triggering, pH internal triggering and pH external triggering are used to achieve the realization in the microchannel The rapid gelation and solidification of the dispersed phase droplets ensure the sphericity and uniformity of the γ-alumina microspheres, and the surface is smooth, and the internal pore structure is controllable; the diameter of the γ-alumina microspheres provided by the present invention is 300 ~500μm, the specific surface area is 290~400m.
Apizon modified alumina column has high column efficiency, good separation and symmetrical peak shape.
