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.

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