Cogent Type-C silica HPLC phases have the ability to retain polar solutes at high concentrations of organic solvent by aqueous normal-phase (ANP) and non-polar compounds under reversed-phase (RP) conditions.
The columns use innovative bonding technology to create a surface populated by silicon-hydride functional groups instead of silanols. The lack of surface silanols leads to fast equilibration times, excellent peak shape and extended column lifetimes for a wide range of analytes.
The Cogent range includes Bidentate C18, Bidentate C8, UDC-Cholesterol, Phenyl Hydride, Diamond Hydride and UDA phases. 4 micron and newer 2.o micron columns are available.
