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. Thanks to these features, Purospher® STAR RP-18 endcapped, 3 µm HPLC columns allow maximum flexibility to use the best chromatographic conditions for any separation including reversed phase.Purospher® STAR RP-18 endcapped, 3 µm Hibar® RT 50-3 is a ready to use stainless steel column suitable for connection to any HPLC system.The column dimension of 50 mm length x 3 mm I.D. is the optimal choice for fast HPLC separation of complex samples at lower flow rate, allowing significant solvent savings and improved sensitivity. A 3 mm I.D. column enables a more sustainable separation in comparison to 4 or 4.6 mm I.D. column due to the use of less solvent for the chromatographic separation.The recommended guard column is Purospher® STAR RP-18 endcapped (5 µm) LiChroCART® 4-4 part number 1.50250.0001. For direct connection to a Hibar® RT columns the Precolumn holder for 4-4 LiChroCART® cartridges, part number 1.51487.0001 can be used.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

Application

Intended to be used in the separation of aflatoxins, aldehydes, alkaloids, antibiotics, catecholamines, explosives, oligonucleotides, esters, fat soluble vitamins, lipids, fatty acids, flavonoids, ketones, nitrosamines, nucleosides, PAHs, PCBs, peptides, pesticides, phenols, phthalates, preservatives, steroids, metabolized steroids, sulfonamides, sweeteners, and water soluble vitamins.
