Spherical particles

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.

Very low metal content

As shown in the table, the Surf silica has a very low content in metal..

• Those characteristics results in reproducible packing batch to batch, column to column, either analytical as preparative, allowing longer column lifetime.
• With a specific surface area of 310m2/g and 100Å pore diameter, Surf was developed to display a high load capacity and deal with small to medium molecules (up to 7,000 Da), which is ideal for both analytical and preparative separations.
