The IonPac® CS5A is a high-resolution, ion-exchange column designed for determination of transition and lanthanide metals in a variety of 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.a
The CS5A column provides 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 both sensitive and selective for transition metals.
The CS5A provides improved selectivity and higher efficiencies than its predecessor, the CS5 column.
