Thermo Fisher, 31605-124030, Hypersil™ ODS-2 C18 Columns

Hypersil™ ODS-2 C18 Column 31605-124030 is used for conventional reversed-phase HPLC, particularly where established methods specify a classical C18 packing. This configuration is 125 mm long with a 4 mm internal diameter and contains 5 µm spherical, fully porous Type A silica particles. The endcapped C18 stationary phase has an 80 Å pore size, 220 m²/g surface area and 11% carbon load. It carries USP L1 classification and is intended for HPLC use at pressures up to 5800 psi (400 bar). The phase operates over pH 2–8 and up to 60 °C. Hypersil ODS-2 is useful for routine small-molecule separations and for maintaining older or validated reversed-phase methods that were developed with traditional ODS materials. The familiar 5 µm particle format and conventional silica chemistry make this column practical for method transfer, method maintenance and laboratories that need dependable C18 selectivity rather than a newer alternative stationary phase.
