Dionex Ion-Pair 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.
