Purospher® STAR RP-18 endcapped (5 µm) is used for reversed-phase HPLC separation of basic, neutral and metal-chelating compounds across analytical workflows. This ready-to-use Hibar® RT column measures 250 mm × 4.6 mm and contains 5 µm fully porous, ultra-pure silica particles bonded with an endcapped C18 phase. The stationary phase has a 120 Å pore size, approximately 330 m²/g surface area and 17% carbon loading. The stainless-steel column supports operation up to 400 bar and 65°C, with a stated pH range of 1.5–10.5. It is suitable for HPLC and LC/MS use, complies with the USP L1 stationary-phase classification and can operate with highly aqueous mobile phases without phase collapse. The 250 mm length provides a high-resolution format for demanding reversed-phase separations and method development involving complex mixtures.
