The SFC Viridis columns, from Water Corporation, are available in two chemistries: 2-ethylpyridine and silica. The columns feature Water Corporation’s Optimum Bed Density (OBD(TM)) technology, which is designed to produce mechanically stable columns with longer lifetimes.
SFC typically uses carbon dioxide (CO2) as the main ‘supercritical’ mobile phase. As a chromatographic mobile phase, CO2 is a low-cost solvent alternative to the organic solvents typically employed in the laboratory and is inert by nature and therefore safer to use. Using CO2, laboratories will typically experience a 70-95% reduction in solvent purchase and disposal costs over organic solvents.
