Torus™ Columns, manufactured by Waters™, are designed for achiral SFC separations. They offer a wide range of selectivity, excellent peak shape, and are suited for method transfer and method scale-up. Torus™ Columns are offered in 1.7 and 5 μm chemistries in both analytical and preparative column formats. The Torus™ Phases are based on spherical, ethylene bridged hybrid (BEH) particles.
