An all round and fully-porous, scalable spherical Silica from 1,5 to 15 µm with a high purity.

The metal content is less than 100 ppb. The silica impresses with its very narrow pore size distribution this make 99% of the surface accessible for the separation. The uniform bonded phase coverage translates to symmetrical peaks for acids/bases, and predictable reversed phase selectivity. Because of its very low metal content it also impressed with a high pH stability.
