Restek Viva Silica 5um, 150 x 4.6mm

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

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. 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 available surface area for large molecules. Viva silica features a narrow pore size distribution, enabling more effective separations by maximizing surface accessibility.

Base-deactivated spherical silica is useful for normal-phase or HILIC separations.
