Dionex™ AS4A Eluent Concentrate; Sodium Carbonate/Bicarbonate Concentrate (100X)

For fast, reliable anion eluent preparation, the ready-to-dilute Thermo Scientific™ Dionex™ AS4A Eluent Concentrate; Sodium Carbonate/Bicarbonate Concentrate will save you time and eliminate the worry of potential contamination or preparation error. For use with Dionex™ IonPac™ AS4A, AS4A-SC, and AS9-SC columns, simply prepare eluent by dissolving the concentrate in deionized water. The 100x concentrate is made with only high purity, reagent grade chemicals and water (18 MO-cm) and quality checked for ionic contamination. The concentrate contains 0.18M carbonate and0.17M bicarbonate.

• The IonPac™ AS4A/AS4A-SC/AS9-SC eluent concentrate is available for anion applications as a 100X concentrate containing 0.18M carbonate/0.17M bicarbonate Recommended for fast, reliable eluent preparation
• Dilute in deionized water to save time and eliminate the worry of inaccurate eluent preparation and contamination
• 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 reliable method of analysis such as ion chromatography, UV spectrophotometry (using NIST or USP Reference Material where applicable), titration (using NIST Reference Material) and gravimetric preparation
