|
The Metrosep C 4 - 50/4.0 is the shortest separation column in the Metrosep C 4 product range. With a capacity of 6 µmol (K
+), it is particularly suitable for very rapid separations. The low capacity makes it possible to quickly analyze the earth alkaline metals with their delayed elution. Thanks to the short retention times, applications that, in terms of analysis duration, were previously possible only with an FIA system (Flow Injection Analysis system) can now be transferred over to ion chromatography.

| 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.
