Metrosep C 4 - 250/4.0

6.1050.430 Metrosep C 4 - 250/4.0
Cation separation column for the determination of monovalent and bivalent cations with improved peak forms, greater efficiency resulting in lower detection limits. PEEK column.
 
6.1050.430 Metrosep C 4 - 250/4.0

The Metrosep C 4 - 250/4.0 is the cation column with the greatest capacity in the C 4 series. It is predestined for applications which require the highest separating efficiency. Samples with extreme differences in concentrations can be analyzed reliably with this column. The performance capability of the column is demonstrated, for example, in connection with the analysis of boiler feed water for which the requirement is the perfect quantification of 7 µg/L sodium in addition to 7 mg/L monoethanolamine (MEA). With the C 4 - 250/4.0, not only amines and transition metals but also alkaline and alkaline earth metals can be determined in a single run.

Regeneration

Disconnect the column outlet from the detector inlet.

The column must be rinsed with ultrapure water before and after the regeneration.

Organic contamination:
Rinse the column opposite the flow direction at a flow rate of 0.9 mL/min; 1 h with ultrapure water, 1 h with acetonitrile/water (40/60), 1 h with ultrapure water.

Inorganic contamination:
Rinse the column opposite the flow direction with 10 mM HNO 3 + 4 mM dipicolinic acid for 1 h at a flow rate of 0.9 mL/min.
