Everest columns have unique selectivity and sensitivity, which are the result of bonding technology that improves C18 surface coverage and deactivates residual silanols.

• Unique selectivity for hydrophilic and hydrophobic peptides
• High resolution for complex peptide digests
• Excellent sensitivity with little or no TFA in mobile phase
• USP L1

Vydac 238EV (C18) offers maximum surface coverage for the highest resolution of complex samples. It is recommended for the analysis of complex enzymatic digests (>12 proteins).

Previously, the best 300 Å C18 chemistries have had carbon coverage in the 2.8 to 3.6 µmoll/m² range. Everest C18 coverage is in excess of 4 µmol/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.
