Metrosep A Supp 4 - 250/2.0

Metrosep A Supp 4 - 250/2.0
Order Number: 6.01021.230

The Metrosep A Supp 4 - 250/2.0 microbore column 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 - 250/2.0 has a medium ion exchange capacity and is particularly suitable for all routine tasks in water analysis.
