Purospher® STAR RP-8 Endcapped Hibar® RT
Inner Diameter (I.D.): 4.6 mm
Length: 250 mm
Package Contents: 1 Column
Purospher® STAR RP-8 endcapped, like Purospher® STAR RP-18 endcapped, is based on high purity silica and 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 additon, Purospher® STAR RP-8 endcapped columns offer a wide applicability. 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
polar compounds. Like all other Purospher® HPLC columns, Purospher® STAR RP-8 endcapped columns are available in
a large number of different hardware formats.
Purospher® STAR RP-8 endcapped benefits
- Enhanced selectivity for positional isomers
- Excellent peak symmetry for polar and basic compounds
