Purospher STAR RP-18 endcapped is the most modern high-purity silica sorbent for HPLC manufactured by Merck KGaA.
It has the highest efficiency in terms of the number of theoretical plates; the ultra high purity of 99.9999 % ensures excellent peak symmetry for acidic, basic and even for chelating compounds.
Purospher STAR RP-18 endcapped columns are available in a large number of different hardware formats.
The very good all-round retention characteristics, as demonstrated by the Tanaka Test, makes Purospher STAR RP-18 endcapped a column packing material, which is truly "Easy to Choose, Easy to Use" - our recommendation as the first column of choice whenever a new HPLC method has to be developed.
