General description
Purospher® STAR RP-18 endcapped, 3 µm HPLC columns are designed for universal use and allow the separation of basic, neutral, and metal chelating compounds with simple mobile phases and excellent peak symmetry. They are based on ultra-pure fully porous silica particles (Type B). These columns offer an outstanding stability from pH 1.5 to 10.5 over a wide temperature range, and suitability for up to 100% aqueous mobile phases. Plus, they demonstrate best all-round retention characteristics, as proven by the Tanaka test. Purospher® STAR RP-18 endcapped, 3 µm Hibar® HR 30-2.1 is a ready to use UHPLC column suitable for connection to any UHPLC system providing a pressure stability of 1000 bar.The column dimension of 30 mm length x 2.1 mm I.D. is the optimal choice for rapid UHPLC separation of complex samples allowing significant solvent savings and improved sensitivity.Learn more about Purospher® STAR HPLC and UHPLC ColumnsLearn more about the Supelco HPLC Column portfolio and Method development:Brochure: HPLC and UHPLC Column Selection GuideBrochure: A Practical Guide to HPLC – Method Development Guide
