Description

General description

Purospher^® STAR Si endcapped, 5 µm HPLC columns offers highest separation efficiency for normal-phase chromatography of low molecular weight compounds soluble in organic solvents.Purospher^® STAR Si, 5 µm Hibar^® RT 250-4.6 is a ready to use stainless steel column suitable for connection to any HPLC system.The recommended guard column is Purospher^® STAR Si (5 µm) LiChroCART^™ 4-4 part number 1.50249.0001. For direct connection to a Hibar^® RT columns the Precolumn holder for 4-4 LiChroCART^™ cartridges, part number 1.51487.0001 can be used.The column dimension of 250 mm length x 4.6 mm I.D. is the optimal choice for the HPLC 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

Application

Intended to be used in the separation of aflatoxins, carotenoids, oils, fat soluble vitamins, lipids, and fatty acids.

Features and Benefits

• Ultra-pure silica (99.999%) for excellent peak symmetry
• High separation efficiency
• Reproducible results from run-to-run and batch-to-batch
• Use with Normal-phase or HILIC conditions (needs to be flushed to HILIC mobile phase)
• Good suitability for LC-MS applications
