Thermo Scientific™ Dionex™ 4-(2-Pyridylazo) Resorcinol Monosodium Salt (PAR), 5g is used for post–column derivitization of transition metals separated on the IonPac CS5A column.
The MetPac™ PAR Post–column Reagent Diluent is a ready-to-use diluent for 4-(2-pyridylazo) resorcinol for post–column derivitization of transition metals separated on the IonPac CS5A column
Prepared by the dissolution of high-purity chemicals in >18.2MΩcm deionized water, which was tested by ion chromatography for ionic contaminants
Bottle label states the nominal concentration value for informational purposes only
Actual concentration is within ±2.5% and was determined by one or more 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
