Waters, PSS831913, Spherisorb ODS2 Column, 80Å, 5 µm, 4.6 mm X 150 mm, 1/pk

Waters Spherisorb ODS2 C18 HPLC Column is an analytical reversed-phase column for separation of small organic molecules in conventional HPLC methods. Its silica packing has 80 Å pores and 5 µm spherical particles contained in a 4.6 mm internal-diameter, 150 mm long column. The ODS2 stationary phase has an intermediate C18 ligand density, approximately 11.5% carbon loading, and endcapped surface chemistry. These features create a retention profile different from the less densely bonded, non-endcapped Spherisorb ODS1 material. This distinction is especially important when replacing a column in a validated analytical method, because matching the general C18 designation alone does not ensure comparable selectivity. Operate within the specified pH range of 2 to 8 and maximum pressure of 415 bar. Prepare filtered, miscible mobile phases and equilibrate the stationary phase before injecting standards and samples. Monitor retention, peak symmetry and pressure during routine operation to detect changes in system performance. This package contains one analytical HPLC column, without a guard cartridge or solvent supply.
