Application Note

Discovery® C18 HPLC Column is used for routine reversed-phase HPLC and LC-MS analyses requiring classic C18 selectivity in a shorter analytical format. This configuration measures 12.5 cm × 4 mm and contains 5 µm high-purity spherical fully porous silica particles with 180 Å pores. The endcapped C18 phase carries approximately 12% carbon loading and corresponds to USP L1. The stationary phase operates over a stated pH range of 2–8, and the column supports pressures up to 400 bar and temperatures up to approximately 70°C. The 125 mm bed length can reduce analysis time and solvent consumption relative to longer Discovery C18 columns while retaining the same stationary-phase chemistry. The column is suitable for acidic, basic and neutral analytes and for LC-MS workflows requiring low bleed.
