The performance of Surf columns and packings comes from the ultra-high quality and purity of our silica (99.99%) and extremely low metal content – less than 10 ppm in total.
Surf silica particles are spherical and exhibits a uniform surface and extremely narrow size distribution.
Strict quality control guarantees consistent pore sizes and pore structure, enabling high mechanical strength and enhanced bed stability.
As shown in the table, the Surf silica has a very low content in metal..
