Viva C4 HPLC Column, 5um, 150 x 3.0mm

Viva HPLC Columns: 3 or 5 µm particles; 300 Å pore size 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. 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. Particle Size: 5 µm, spherical Pore Size: 300 Å Carbon Load: 3.5% End-Cap: yes pH Range: 2.5 to 8 Temperature Limit: 80°C USP Phase Code: L26 Phase Category: C4, butylsilane Ligand Type: monomeric C4
