Restek Viva C18 3um, 150 x 2.1mm

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 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.

The general-purpose Restek C18 is a conventional monomeric octadecylsilane column suitable for analyses of a wide range of compounds from acidic through slightly basic.
