General Description

Purospher® STAR RP-8 endcapped, 5 µM HPLC columns allow the separation of basic, neutral, and metal chelating compounds with simple mobile phases and excellent peak symmetry. They are based on ultra-pure fully porous silica particles (Type B). These columns offer an outstanding stability from pH 1.5 to 10.5 over a wide temperature range. Purospher^®STAR RP-8 endcapped, 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 1.50270.0001. 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 RP-8 endcapped, 5 µM Hibar^®RT 125-4 HPLC columns are available part number 1.50033.0001.The column dimension of 125 mm length x 4 mm I.D. is the optimal choice for the HPLC separation of complex samples.Item 1.50271.1003 is a Validation kit containing 3 Purospher^®STAR RP-8 endcapped, 5 µM LiChroCART^®125-4 cartridge 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
