Fast method development of complex samples across the pH range from 1,5 to 10,5 with different mobile phases and temperature conditions.
Purospher® STAR RP-18 endcapped HPLC columns are designed for universal use. Basic, neutral and metal-chelating compounds can easily be separated with simple mobile phases – naturally without peak tailing. Thanks to its outstanding performance and stability, Purospher® STAR RP-18 endcapped offers maximum flexibility in method development. Robust methods can be developed over the entire pH range from 1,5 to 10,5. High pH-stability allows the separation of strongly basic compounds with alkaline eluents. The combination of high purity silica, best all-round retention characteristics, outstanding pH stability up to pH 10,5, and suitability for up to 100% aqueous mobile phases, make Purospher® STAR RP-18 endcapped an all-round top performance column, almost universal in its range of applications.

• Highest silica purity (99,999%) for excellent peak symmetry
• High separation efficiency
• Absolutely reproducible results from run-to-run and batch-to-batch
• Best all-round RP selectivity
• No phase collapse when using highly aqueous mobile phases
• Good suitability for LC-MS applications

These cartridges require 1.51486.0001 manu-CART® cartridge column holder, which can be used to hold one cartridge column with or without a 4×4 mm guard column. LiChroCART® columns 250×10 mm require 1.51419.0001 manu-CART® 10. Short LiChroCART® columns can be ordered as a set, including the corresponding cartridge holder and one cartridge, or as a pack of three cartridges without cartridge holder. The separate part numbers for the cartridge are: 1.50227.0001 LiChroCART® cartridge holder for 30 mm cartridge and 1.50226.0001 LiChroCART® cartridge holder for 55 mm cartridge.

The Hibar® RT columns are complete with end fittings. When using a guard column with a Hibar® RT column, we recommend 1.51487.0001 guard column cartridge holder for 4×4 mm guard column cartridges LiChroCART®.
