Restek Viva PFPP 5um, 150 x 3.0mm

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. In developing Viva silica, Restek found that although many commercial wide-pore silicas meet the standard 300 Å mean pore size, most have broad distributions, with significant pore volume below 150 Å. This limits surface area availability for large molecules. Viva columns have a narrow pore size distribution, allowing a larger portion of the silica surface to contribute to separation efficiency.

The Restek PFP Propyl phase provides excellent retention and selectivity for charged bases, electronegative compounds, and amine-containing compounds. Unlike conventional cyano columns, the Restek PFP Propyl is highly compatible with LC-MS applications and acidic mobile phases. It also supports highly aqueous mobile phases and HILIC separations.
