Aqueous SEC (GFC) Diol Binding Silica Column

Aqueous SEC (GFC) Diol Binding Silica Column 

Column Features:

  • 4um Diol Silica Silica High packed column is 1.5 times higher theoretical plate number (32,000 plate number).
  • In comparison with a conventional ID 7.8 mm column, the Chromanik ID 4.6mm Length 300 mm Semi-micron sized packed column, has 3 times the sensitivity and uses 1/3 less solvent.
  • High durability allowing for at least 500 sample injections
  • Employs 2 types of Silica Gel pore sizes of 30nm and 15 nm.

Applications:  Proteins, enzymes, peptides, sugars, and nucleic acids

SunSec Diol 30 has a pore diameter of 30nm.  Compared to other company’s   25 nm pore diameter SunSec Diol 30 has double the molecular weight exclusion limit.  This has advantages for separation of dimer /trimer monoclonal antibodies.
