HPLC Guard Cartridge Vydac EVEREST 5µm C18 (for 2.1mm id) 2pk, old no: 238GD52EV

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 300 Å C18 chemistries had carbon coverage in the 2,8 to 3,6 µmol/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.

Please note that these columns have been manufactured by Hichrom / Avantor since 2016
