Metrosep A Supp 4 - 250/4.0

Metrosep A Supp 4 - 250/4.0
Beställningsnummer: 6.1006.430

The Metrosep A Supp 4 - 250/4.0 is an extremely robust column with very good separation properties. The separation phase is comprised of polyvinyl alcohol particles with quaternary ammonium groups and a diameter of 9 µm. This structure guarantees great stability and a greater tolerance to very small particles that could pass through the integrated filter pad. The Metrosep A Supp 4 - 250/4.0 has a medium ion exchange capacity; sulfate elutes after 12.5 minutes. The plate numbers that can be achieved with this separation column are higher than those for the Metrosep Anion Dual 2 - 75/4.6. The A Supp 4 - 250/4.0 is particularly suitable for all routine tasks in water analysis.
