Waters, WAT011695, Nova-Pak C18 Column, 60Å, 4 µm, 3.9 mm X 300 mm, 1/pk

Waters Nova-Pak C18 is a silica-based reversed-phase HPLC column for general-purpose analytical separations. Its C18 bonded phase provides hydrophobic retention, and the 4 µm particle technology supports efficient resolution of multi-component samples. It is a conventional reversed-phase analytical column rather than a size-exclusion or ion-exchange device. The column measures 3.9 mm internal diameter by 300 mm length and uses 4 µm spherical silica particles with a 60 Å pore size. The bonded phase is endcapped and has a 7% carbon load. Its pH operating range is 2–8, while the maximum pressure rating is 6,000 psi (415 bar). The long 300 mm bed provides chromatographic resolving length when a method calls for the matching dimensions and pressure capability. Nova-Pak C18 carries USP classification L1, and the unit is sold as one column per package. Select mobile phases and sample conditions suitable for silica-based C18 packing, and observe the validated method when replacing an existing column.
