TN10: Determination of Transition Metals by Ion Chromatography Using PDCA Eluent

Instrument Type: IC

The IonPac CS5A column has both cation and anion exchange capacity, allowing metals to be separated as cations or anions on a single column. This is called a mixed mode separation.Transition metals are separated as anionic complexes with the PDCA chelating agent added to the eluent. The metals are detected by measuring the absorbance at 530 nm of the complex formed with the postcolumn PAR reagent.
