The performance of the Surf columns comes firstly from the quality of the silica used.
The natural silica of the Surf columns is composed of homogenously sized spherical particles.
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.
The narrow distribution of particle size, combined with a specific surface and an optimal pore volume allows for robust particles with excellent retention characteristics.
