Description

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).
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^™ 250-2 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 guard column.
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 250-2 HPLC columns are available part number 1.50598.0001.
For use under UHPLC conditions (where a pressure stability up to 1000 bar is required) it is recommended to use a Purospher^® STAR RP-18 endcapped, 3 µm Hibar^® HR 250-2.1 UHPLC Column part number 1.50655.0001
The column dimension of 250 mm length x 2 mm I.D. is the optimal choice for HPLC separation of complex samples at lower flow rate, allowing significant solvent savings and improved sensitivity
