Overview
Features & Benefits
- Excellent for separating peptides or proteins
- Rugged, spherical particles with 300 Å pore size
- High proportion of pore/surface area available to large molecules
Note: Guard column requires Trident LC column protection system or Trident HPLC in-line guard cartridge holder.
Description
Viva columns are based on a wide-pore material designed for optimal large-molecule separations. During development, it was found that many commercial wide-pore silicas meet the standard 300 Å mean pore size but have broad distributions, with significant pore volume below 150 Å. This reduces the available surface area for large molecules. Viva silica features a narrow pore size distribution, allowing more of the silica surface to participate in separations.
Base-deactivated spherical silica is useful for normal-phase or HILIC separations.
