... a family of totally porous silica

An absolutely reliable choice in HPLC

Nucleosil is available in a wide range of pore sizes. Nucleosil 100Å has the greater capacity whilst the 120Å material exhibits the lower column back pressure. The 300A silica columns are used for bioanalytical separations.
