微粒硅胶作为高压液体色谱固定相,由于它的颗粒细而匀,便于填充均匀的柱床,而且固定相表面不像大颗粒硅胶那样多的细而深的“液坑”,因而溶质分子在颗粒之间行程短,传质快,柱效高。无定形全多孔微粒硅胶是近年来刚问世的产品,它不仅具有较高的柱效率和分离能力,而且有较大的样品容量和峰容量,综合了薄壳型固定相传质快和全多孔型固定相样品容量大的优点,所以很受欢迎。我国青岛海洋化工厂生产了这种硅胶,它
As a high-pressure liquid chromatographic stationary phase, microparticulate silica gel is characterized by its fine and even particles, which is convenient for filling a uniform packed bed, and the surface of the immobilized phase is not as deep and thin as the large liquid silica gel, Short trip, mass transfer fast, high column efficiency. Amorphous all-porous micro-silica gel has just come out in recent years. It not only has high column efficiency and separation ability, but also has a large sample capacity and peak capacity. It combines the advantages of fast mass transfer and full porous type The advantages of large sample size of the stationary phase, so very popular. China’s Qingdao Ocean Chemical Factory produced this silicone, it
