Descripción

Descripción general

Purospher^® STAR Phenyl, 2 µm UHPLC columns are the best alternative to RP-8 or RP-18 columns for the high-resolution separation of aromatic compounds, and compounds containing aromatic groups. Purospher^® STAR Phenyl can retain analytes via several different mechanisms, including ο-ο interactions between the overlap of the delocalized electrons on the analyte and the stationary phase phenyl group, and via partitioning between the mobile phase and the hydrophobic aryl-alkyl phase. Our Purospher^® STAR Phenyl columns are based on highpurity silica particles, which provide symmetrical peaks for basic compounds, as well as high stability and excellent reproducibility. Furthermore, hydrophobic compounds elute much faster with Purospher^® STAR Phenyl columns than with C-18 columns.Purospher^® STAR Phenyl, 2 µm Hibar^® HR 50-2.1 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 50 mm length x 2.1 mm I.D. is the optimal choice for high throughputUHPLC 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
