High Resolution for Complex Peptide Digests
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 300Å C18 chemistries have had carbon coverage in the 2.8 to 3.6μmol/m2 range. Everest™ C18 coverage is in excess of 4μmol/m2 and approximates the theoretical limit based on surface area. This increased shielding of the base silica increases column life and reduces the amount of TFA required to shield the silica.
