Metrosep A Supp 10 - 100/4.0

Metrosep A Supp 10 - 100/4.0
Order number: 6.1020.010

The Metrosep A Supp 10 - 100/4.0 separation column is based on a high-capacity polystyrene/divinylbenzene copolymer with a particle size of only 4.6 µm. This column is characterized by high plate numbers and high selectivity. Sulfite and sulfate thus can be reliably separated in the eluent without the addition of organic modifiers. These characteristics are supplemented by great flexibility with respect to column temperature, flow and the composition of the eluent.

Its robust construction, excellent price-performance ratio and very good separating efficiencies, in conjunction with moderate chromatography times, make the Metrosep A Supp 10 - 100/4.0 a universally applicable anion separation column.
