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 LiChroCART™ 125-4 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. The column dimension of 125 mm length x 4 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

Analysis Note

Pressure: ≤ 30 bar
Theoretical Plates (N/m) (2-Nitrotoluene): ≥ 65000
Symmetry (2-Nitrotoluene): 0.8 - 1.4
Capacity factor (2-Nitrotoluene): 0.5 - 2.0
