Purospher® STAR RP-8 endcapped, like Purospher® STAR RP-18 endcapped, is based on high purity silica and has an almost complete surface coverage. Thus, Purospher® STAR RP-8 provides excellent peak symmetry for acidic, basic and even chelating compounds, highest column efficiency in terms of the number of theoretical plates, and exceptional stability from pH 1,5 to 10,5. In addition, they are ideal for a wide range of applications. As the sorbent is less hydrophobic than Purospher® STAR RP-18 endcapped, analytes will typically elute faster on the C8 phase. Purospher® STAR RP-8 endcapped provides enhanced selectivity for positional isomers and symmetrical peak shapes for strongly basic and less hydrophobic compounds.

• Enhanced selectivity for positional isomers
• Excellent peak symmetry for polar and basic compounds

These LiChroCART® 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.

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