Dionex IonPac CP1 Na+ and CP2 H+ cation purification columns are designed to remove metal contaminants and other cations (such as calcium and magnesium) from the sample stream during anion analysis. This type of cleanup column can prevent high concentrations of metals or cations in the sample from depositing on the column or suppressor, resulting in reduced performance (such as worse peak shape or lower anion recovery).
Dionex IonPac CP1 Na+ type cation purification column suitable for anion analysisDionex IonPac CP1 Na+ type purification column is a sodium ion type cation exchange column packaged in low pressure specifications . Designed for use with autosamplers.
- 1 size (6x16mm) to fit all applications
- Dead volume: ∼250µL
- Column capacity: 170µeq
Dionex IonPac CP2 H+ Cation Purification Column for Anion AnalysisThe Dionex IonPac CP2 H+ Purification Column is a higher capacity version of the Dionex IonPac CP1 Na+ Purification Column, packaged in a hydrogen ion type . Recommended for preconcentration applications of large sample volumes using an external pump.
- 1 size (9x24mm) to fit all applications
- Dead volume: ∼825µL
- Column capacity: 575µeq
Note: Both cation purification columns can be regenerated offline every 2-3 months, depending on the concentration of pollutants and usage.
