Purospher STAR RP-8 endcapped, like Purospher STAR RP-18 endcapped, is one of the most modern high-purity silica sorbents for HPLC manufactured by Merck KGaA.

It has the highest efficiency in terms of the number of theoretical plates; it has the widest pH range, even up to pH 10.5; it has the highest purity - trace metals levels are below 5ppm in total, ensuring excellent peak symmetry for acidic, basic and even for chelating compounds.

Purospher STAR RP-8 endcapped columns are available in a large number of different hardware formats.
