Superspher® columns are specially designed for highly efficient HPLC separations. According to both theoretical calculation and practical experience, these high performance spherical silica carriers, with a mean particle size of 4 μm, provide an optimum pressure to separation performance ratio. The number of theoretical plates for Superspher® HPLC columns is > 100,000 N/. This makes them the ideal choice for complex sample mixtures that require high peak capacity.
