Cogent HPLC columns have a silicon hydride surface similar to other TYPE-C™ phases but the uniqueness of Phenyl Hydride™ is that they have unique selectivity for compounds with aromatic rings with all the TYPE-C silica benefits.

Supplier: Thermo Fisher Scientific

The Zeba™ Desalting chromatography cartridges, 7 kDa MWCO, contain a high-performance resin for desalting or buffer exchange applications. This resin is ideal for removing low molecular weight compounds including salts, fluorescent dyes, biotin and other small labeling reagents. Zeba™ Desalting Cartridges provide fast, easy and reproducible chromatographic separations and can be regenerated for multiple uses. They efficiently process samples from 50 to 1500 µl.

Supplier: Avantor

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.
