MicroSolv Technology Corporation have introduced Cogent 2.o micron Type-C silica LC columns.

Type-C silica columns have a surface populated by silicon-hydride functional groups instead of silanols. These bonded 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 conditions. The lack of surface silanols leads to fast equilibration times, excellent peak shape and extended column lifetimes. The Cogent range includes Bidentate C18, Bidentate C8, UDC-Cholesterol, Phenyl Hydride, Diamond Hydride and UDA phases.
