    Metrosep A Supp 4 - 250/4.0

    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 which 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 number of plates which can be achieved with this separation column is higher than those on 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.

    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 which 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 number of plates which can be achieved with this separation column is higher than those on 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. Its universal applicability makes it the standard column for the 883 Basic IC plus.

    To protect the IC separation column – even though it is not particularly sensitive to contamination – we recommend the use of the Metrosep A Supp 4/5 Guard/4.0 or the A Supp 4/5 S-Guard/4.0.
