• Excellent for separating peptides or proteins.
• Rugged, spherical particles with 300 Å, pore size.
• High proportion of pore/surface area available to large molecules.

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 columns have a narrow distribution around the mean pore size, permitting a larger portion of the silica surface to play a role in the separation.

Note: We strongly recommend that you only order a semi-preparative or preparative column once you have evaluated the desired separation on an equivalent column on an analytical scale.
Because we cannot reuse a column or the silica within it once it leaves our facility, we cannot accept returns of large columns.
