VivaWidePoreColumns: 3μmor5μmparticles; 300Åpore size
• Excellent for separatingpeptides or proteins.
• Rugged, spherical particles,with300Åpore size.
• Highproportionof pore/surface area available to largemolecules.
Vivacolumns arebasedonawideporematerialwedesigned foroptimal largemolecule
separations. IndevelopingViva silica,we found that althoughmany commercial wide-
pore silicasmeet the standard300Åmeanpore size,most haveverybroaddistributions
about this mean, with a significant portion of their pore volume falling below 150Å.
Thismeans a large portion of the surface area is unavailable to largermolecules.Viva
columns have a narrow distribution around the mean pore size, permitting a larger
portionof the silica surface toplay a role in the separation.
