There are many factors which influence successful flash column chromatography. One of those factors is sample load, which itself is influenced by things like selectivity, efficiency, dissolution solvent, and load technique. Several of these factors I have addressed in previous posts. Of these, selectivity and efficiency are specific to a media's physical and chemical characteristics.
In this post I will show if particle size and/or particle shape can influence loading capacity. Additionally, I will show the positive impact that surface area has on flash column chromatography purification.
