Oversikt over funksjoner

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.

Tekniske spesifikasjoner

ApplicationRange	Applications: Li⁺, Na⁺, K⁺, Mg²⁺, Ca²⁺, Sr²⁺, Ba²⁺, NH₄⁺ Samples with low concentrations Good Na+/NH₄⁺ 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 .

- Metrosep C Supp 2 Guard/4.0
- 6.01053.500
- The Metrosep C Supp 2 Guard/4.0 contains the C Supp 2 column material and is used to protect Metrosep C Supp 2 cation columns. Particles and contamination are reliably retained, considerably prolonging the service life of the analytical separation column. The Metrosep C Supp 2 Guard/4.0 also works based on the "On Column Guard System" and is screwed directly onto the separation column with virtually no dead volume.
