Viva Wide Pore Columns
restek innovation!
Viva silica has a narrow distribution around
the mean pore size, permitting a larger
portion of the silica surface to play a role
in the separation of large molecules and
biomolecules.

Viva Wide Pore Columns: 3μm or 5μm particles; 300Å pore size
• Excellent for separating peptides or proteins.
• Rugged, spherical particles, with 300Å 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 300Å mean pore size, most have very broad distributions
about this mean, with a significant portion of their pore volume falling below 150Å.
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.
