Descrição

Descrição geral

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 LiChroCART^™ 250-4.6 is a cartridge column which requires a manuCART^™ cartridge column holder part number 1.51486.0001. The manuCART^™ can be used to hold one cartridge column with or without direct integration of a 4-4 mm guard column. The recommended guard column is Purospher^® STAR RP-8 endcapped (5 µm) LiChroCART^™ 4-4 part number 1.50249.0001. 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 Si, 5 µm Hibar^® RT 250-4.6 HPLC columns are available part number 1. 51911.0001.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

Aplicação

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

Características e benefícios

• 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
