Metrosep C Supp 2 - 250/4.0

Metrosep C Supp 2 - 250/4.0
Order number: 6.01053.430

The longest separation column in the Metrosep C Supp 2 product range is the Metrosep C Supp 2 - 250/4.0. The Metrosep C Supp 2 separation material is based on a polystyrene/divinylbenzene copolymer with carboxyl groups. Thanks to the optimized sodium/ammonium separation of this separation material, this column is perfectly suitable for determination of the smallest concentrations of ammonium in addition to a large amount of sodium. The column is used with sequential suppression. It is accordingly particularly suitable for the determination of concentrations in the middle µg/L range and below.
