Properties of Vydac Everest Column

Vydac Everest Columns have unique selectivity and sensitivity, which are the result of bonding technology that improves C18 surface coverage and deactivates residual silanols. Previously, the best 300A C18 chemistries have had carbon coverage in the 2.8 to 3.6umol/m2 range. Everest C18 coverage is in excess of 4umol/m2 and approximates the theoretical limit based on surface area. The increased shielding of the base silica increases column lifetime and reduces the amount of TFA required to shield the silica.

The general features of Vydac Everest include:
Unique selectivity for hydrophilic and hydrophobic peptides
High resolution for complex peptide digests
Excellent sensitivity with little or no TFA in mobile phase
