Purospher RP-18 is supplied by Merck

Purospher RP-18 endcapped is a versatile HPLC column producing excellent peak shapes, designed for both the separation of basic compounds with simple neutral eluents and for the elution of strongly acidic compounds.

Excellent separations in a shorter period of time with very good peak symmetry saves time and money.

The excellent balance of Purospher RP-18 endcapped in the sum of its chromatographic properties is the key to better separations of complex samples with simpler, neutral eluents.

Purospher RP-18 endcapped is based upon a high-purity, metal free silica with a complete C18 coverage of the silica surface. This enables a peak-tailing free elution of acidic, basic and chelating compounds.

The good chemical stability of Purospher RP-18 endcapped enables the use of mobile phase conditions at pH 8 for a long period of time.
