Dionex™ AS29 Eluent Concentrate, Sodium Carbonate/Bicarbonate Concentrate (100x)

Save time and reduce preparation errors and contamination that may occur during eluent preparation with the ready-to-dilute Thermo Scientific™ Dionex™ AS29 Eluent Concentrate. For use with Dionex IonPac AS29-Fast-4μm IC columns, simply prepare eluent by diluting the concentrate in deionized water. The 250mL bottle of 100x concentrate is made with only high purity, reagent grade chemicals and water (18.2 MΩ-cm), and quality checked for ionic contamination. The concentrate contains verified concentrations of 0.45M carbonate and 0.20M bicarbonate.

• Dionex AS29 Eluent Concentrate is available for anion applications as a 100x concentrate containing 0.45M carbonate / 0.20M bicarbonate.
• Recommended for fast, reliable eluent preparation.
• Prepared by the dissolution of high-purity chemicals in greater than 18.2 MΩ-cm deionized water, which was tested by ion chromatography for ionic contaminants.
• Bottle label states the nominal concentration value for informational purposes only.
• Actual carbonate concentration is within ±2.5%; actual bicarbonate concentration is within ±5.0%.
• Actual carbonate/bicarbonate concentrations are 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.
• A Certificate of Analysis is included with each bottle.
