Description

General description

Purospher^® STAR RP-8 endcapped, 5 µm HPLC columns 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. Purospher^® STAR RP-8 endcapped, 5 µm Hibar^® RT 250-4 is a ready to use UHPLC column suitable for connection to any HPLC system.The column dimension of 250 mm length x 4 mm I.D. is the optimal choice for the HPLC separation of complex samples.Item 1.50035.1003 is a Validation kit containing 3 Purospher^® STAR RP-8 endcapped, 5 µm Hibar^® RT 250-4 columns from 3 different base material lots.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
