Viridis
Waters™ Viridis™ SFC Columns
Viridis™ Columns, manufactured by Waters™, are designed for achiral SFC separations. They offer an added range of achiral SFC selectivities. These columns are based on the Ethylene Bridged Hybrid (BEH) particle technology, Charged Surface Hybrid (CSH) particle technology, High-Strength Silica (HSS) particle technology and other Waters™ chromatographic silica. The reduction and control of surface silanol activity on Viridis™ Particles delivers, under SFC conditions, excellent peak shapes - even for well-retained basic achiral compounds.
