300 Å Pore Size 5 µm Particle Size Pack of 3 RESTEK 951350212 Guard Cartridge for Viva C8 HPLC Column 10 mm Length 2.1 mm ID

RESTEK 951350212 Guard Cartridge for Viva C8 HPLC Column, 300 Å Pore Size, 5 µm Particle Size, 2.1 mm ID, 10 mm Length (Pack of 3):. 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 silica's 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. C8 is a conventional monomeric octylsilane column offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape over a traditional C18 phase. Like our C18, this general-purpose Restek C8 is suitable for a wide range of compounds from acidic through slightly basic. 。 。 。
