General description
Purospher® STAR RP-18 endcapped, 5 µm HPLC columns are designed for universal use and 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). Purospher® STAR RP-18 endcapped, 5 µm LiChroCART™ 4-4 is a guard cartridge which allows the integration into a manuCART™ cartridge column holder part number 1.51486.0001 for direct, dead volume free connection to a analytical LiChroCART™ cartridge column with inner dimension or 2, 3, 4, or 4.6 mm I.D. and a column length of 75, 100, 125, 150 or 250 mm.For direct connection to a Hibar® RT columns the Precolumn holder for 4-4 LiChroCART™ cartridges, part number 1.51487.0001 can be used.For connection to any other analytical HPLC column with capillary connection the Precolumn holder for 4-4 LiChroCART™ cartridges, part number 1.16217.0001 is suitable.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
