Chromatograms / Specifications / Order Info / Data Sheets

The IonPac CS5A is a high-resolution, ion-exchange column designed for the determination of transition and lanthanide metals in diverse sample matrices. The CS5A column, in combination with postcolumn derivitization and visible detection at 530 nm, provides a sensitive and selective method for transition metal analysis.

The CS5A column is recommended for the separation of transition and lanthanide metals.
The CS5A can also be used for aluminum analysis.

The CS5A column permits the simultaneous determination of common transition metals in less than 11 min using a unique bifunctional resin. The transition metals are detected following complexation with 4-(2-pyridylazo) resorcinol (PAR). The PAR derivative is detected at 520–530 nm. This method is very sensitive and selective for the transition metals. The CS5A provides improved selectivity and higher efficiencies than the CS5 column. Use the MetPac^TM PDCA and Oxalic Acid Eluent Concentrates and PAR Postcolumn Reagent Diluent for simplified operation.
