Viva C4 HPLC Columns, Restek

Chromatography Columns

Viva columns are based on a wide pore material we designed for optimal large-molecule separations.

USP L26
Excellent for separating peptides or proteins
Rugged, spherical particles with 300 Å pore size
High proportion of pore/surface area available to large molecules

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.

Base-deactivated, wide-pore packing exhibits excellent peak shape for a wide range of compounds. Less retention in reversed-phase assays than Viva C18 or Viva C8.

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.
