一般說明
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). These columns offer an outstanding stability from pH 1.5 to 10.5 over a wide temperature range, and suitability for up to 100% aqueous mobile phases. Plus, they demonstrate best all-round retention characteristics, as proven by the Tanaka test. Purospher® STAR RP-18 endcapped, 5 µm LiChroCART® 250-3 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-18 endcapped (5 µm) LiChroCART® 4-4 part number 1.50250.0001. LiChroCART® cartridge columns mounted with a manuCART™ cartridge column holder are hand-tight only and have therefore a maximum pressure stability of 250 bar. For higher pressure stability requirements Purospher® STAR RP-18 endcapped, 5 µm Hibar® RT 250-3 HPLC columns are available part number 1.50620.0001.The column dimension of 250 mm length x 3 mm I.D. is the optimal choice for high resolution HPLC separation of complex samples at lower flow rate, allowing significant solvent savings. A 3 mm I.D. column enables a more sustainable separation in comparison to 4 or 4.6 mm I.D. column due to the use of less solvent for the chromatographic separation.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
