的詳細介紹
IonPac CS5A Transition Metal Column
High-Resolution, Ion-Exchange Column for Transition and Lanthanide Metals in Diverse Sample Matrices
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.
-
Recommended for the separation of transition and lanthanide metals
-
Also useful for aluminum analysis
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. Use the MetPac PDCA
and Oxalic Acid Eluent Concentrates and PAR Postcolumn Reagent Diluent
for simplified operation.
