Allows simpler, time saving methods for reversed phase chromatography of basic compounds: Purospher® RP-18 is a versatile HPLC column designed for the separation of problematic basic compounds with simple neutral eluents. This results in less time and cost because of simpler method optimization. Purospher® RP-18 is based upon a high purity, metal free silica. The multi-step chemical modification and deactivation of the surface…

Excellent peak symmetry with either basic or strongly acidic compounds: 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-1…

Purospher® STAR NH2 is a high purity aminopropyl modified stationary phase.

Purospher® STAR RP-18 endcapped is a versatile high purity reversed phase column increasing the productivity in HPLC. Purospher® STAR RP-18 endcapped provide the power to separate the most difficult of compound mixtures. With up to 150.000 N/m for 3 µm and 100.000 N/m for 5 µm particle size, Purospher® STAR RP-18 endcapped will ensure good base line separations.
