Description

General description

Purospher^® STAR Phenyl, 5 µm UHPLC columns are the best alternative to RP-8 or RP-18 columns for the efficient 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 high purity 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, 5 µm LiChroCART^® 250-4.6 is a cartridge column which requires a manuCART^™ cartridge column holder part number 1.51486.0001. LiChroCART^® cartridge columns mounted with a manuCART^™ cartridge column holder is hand-tight only and have therefore a maximum pressure stability of 250 bar.For higher pressure stability requirements Purospher^® STAR Phenyl, 5 µm Hibar^® RT 250-4.6 HPLC columns are available part number 1.51918.0001. The column dimension of 250 mm length x 4.6 mm I.D. is the optimal choice for HPLC high-resolution separation of complex samples.Item 1.51921.1003 is a Validation kit containing 3 Purospher^® STAR Phenyl, 5 µm LiChroCART^® 250-4.6 HPLC 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
