Viva columns are based on a wide pore material we designed for optimal large-molecule separations.In developing Viva silica, we found that although many commercial wide-pore silicas meet the standard 300 Å mean pore size, most have very broad distributions about this mean, with a significant portion of their pore volume falling below 150 Å.This means a large portion of the surface area is unavailable to larger molecules. Viva…
