Superspher® improves the separation efficiency of HPLC analysis. This high performance spherical silica carrier with a mean particle size of 4 µm yields the best pressure/separation performance ratio in view of today´s generation of HPLC systems and according to theoretical calculation and practical experiance. The guaranteed number of theoretical plates for Superspher® is < 100.000 N/m. Therefore, they are always first choice if complex mixtures demand high peak capacity. A broad range of modifications on Superspher® are available: non-polar derivatives (RP-8, RP-8 endcapped, RP-18, RP-18 endcapped and RP-select B) and polar derivatives (Si 60).
