HPLC Column Viva C18, 300Å, 5 µm, 100 x 1 mm

Viva columns are based on a large-porosity material that we have developed for the optimal separation of large molecules. During the development of Viva Silica, we found that many commercially available large pore silicas, while meeting the standard mean pore size of 300 Å, usually have a very wide distribution around this mean, with a significant pore fraction falling below 150 Å. This means that a large part of the surface is inaccessible to larger molecules. In contrast, Viva columns have a narrow distribution around the mean pore size, making a larger fraction of the silica surface available for separation.

• Excellent for separation of peptides or proteins.
• Robust, spherical particles with a pore size of 300 Å.
• Good accessibility to large molecules due to high pore-to-surface ratio.

The general-purpose Restek C18 column is a conventional monomeric octadecylsilane column suitable for the analysis of a wide range of compounds from acidic to weakly basic.

Stationary phase category: C18, octadecylsilane (L1)

Note: We strongly recommend that you only order a semi-preparative or preparative column once you have evaluated the desired separation on an equivalent column on an analytical scale.
Because we cannot reuse a column or the silica within it once it leaves our facility, we cannot accept returns of large columns.
