The MetPac PDCA Eluent Concentrate uses pyridine-2,6-dicarboxylic acid for the separation of iron (II) and iron (III), copper, nickel, zinc, cobalt, cadmium, and manganese on the IonPac® CS5A column. The MetPac Oxalic Acid Eluent Concentrate uses oxalic acid for the separation of lead, copper, cadmium, cobalt, zinc, and nickel on the IonPac CS5A column.

The MetPac PAR Postcolumn Reagent Diluent is a ready-to-use diluent for 4-(2-pyridylazo) resorcinol for postcolumn derivitization of transition metals separated on the IonPac CS5A column.


Transition Metal Reagents Specifications
Dionex Transition Metal Reagents

Dionex reagents are prepared by the dissolution of high-purity chemicals in >18.2 MΩ-cm deionized water, which was tested by ion chromatography for ionic contaminants. The bottle label states the nominal concentration value for informational purposes only. The actual concentration is within ±2.5% and was determined by one or more of the following proven reliable methods of analysis such as ion chromatography, UV spectrophotometry (using NIST or USP Reference Material where applicable), titration (using NIST Reference Material), and gravimetric preparation.
