General description
Purospher® STAR NH2, 5 µm HPLC columns are widely used for carbohydrate analysis, with a typical mobile phase consisting of acetonitrile and water. Purospher® STAR NH2, 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 an analytical LiChroCART™ cartridge column with inner dimension of 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
