Spherical particles

The natural silica of the Surf columns is composed of homogenously sized spherical particles.

Very low metal content

As shown in the table, the Surf silica has a very low content in metal.
In the following pages, we have chosen to display our columns made from a 100A pore-sized silica, which is the ideal size for small molecules separation..

Our range also features other sizes of pores.
The specific surface of the Surf silica is 310m²/g for 100A.

• High number of theoretical plates per meter.
• Controlled separation, fine peak tailings and optimised analysis duration.

The narrow distribution of particle size, combined with a specific surface and an optimal pore volume allows for robust particles with excellent retention characteristics.
