U/HPLC Separations with Excellent Peak Symmetry

Purospher™ STAR HPLC and UHPLC columns are based on 99.9999 % ultra-pure fully porous silica (Type B). They are designed for universal use and allow the separation of basic, neutral, and metal chelating compounds with simple mobile phases and excellent peak symmetry. 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 HPLC columns allow high-throughput applications, and allow maximum flexibility to use the best chromatographic conditions for any separation including reversed phase.
