Description

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. So it is particularly suitable for determining concentrations in the middle µg/L range and lower.

Specifications

General

ApplicationRange	Applications: Li + , Na + , K + , Mg 2+ , Ca 2+ , Sr 2+ , Ba 2+ , NH 4 + Samples with low concentrations Good Na+/NH 4 + separation Low detection limits Transition metals Excellent peak form Matrix with high pH
Organic Modifier	Eluent: 0 - 100% acetone and acetonitrile (no alcohol) Sample: 0 - 100% acetone, acetonitrile, and alcohols
pH range	Eluent: 0 - 12 Sample: 0 - 14
Regeneration	Note: Ensure that the maximum pressure is never exceeded during regeneration. If the pressure becomes too high, reduce the flow rate. Regeneration: Disconnect the column outlet from the downstream functional units such as suppressor or detector. Instead, collect the flow of liquid in a beaker. Rinse the column with ultrapure water before and after regeneration. Depending on the type of contamination, proceed in accordance with one of the following instructions: Organic contamination : Regenerate the column in the opposite direction to the flow at 1 mL/min with the following solutions in succession: 1 h with ultrapure water 1 h with acetonitrile-water mixture (40:60) 1 h with ultrapure water Inorganic contamination : Regenerate the column in the opposite direction to the flow at a flow rate of 1 mL/min over 1 h with 50 mmol/L nitric acid .
