Sepax CNT Columns
Description
Utilizing proprietary surface technologies, the Sepax CNT SEC phases are made of specially coated
porous silica materials. The silica support has high purity and enhanced mechanical stability. The
Sepax CNT SEC phases have been innovatively and specially designed to ensure highest resolution
and maximum recovery for the separation of nanotubes, such as carbon nanotubes, and nanorods.
The Sepax proprietary surface technology allows extremely high column-to-column reproducibility
and provides exceptional phase stability. The uniform, spherical particles of the Sepax CNT SEC
phases have a nominal pore size at 300 Å, 500 Å, 1,000 Å, and 2,000 Å with the pore volume at ca.
1.0 mL/g. The Sepax CNT SEC phases are packed with a proprietary slurry technique to achieve
uniform and stable packing bed density for maximum column efficiency. Typical applications for the
Sepax CNT SEC columns are the separations of nanotubes in aqueous buffer solutions as well as
normal organic solvents, such as acetonitrile, methanol and THF.
