The Thermo Scientific™ Dionex™ AS22 Eluent Concentrate is a ready-to-dilute sodium carbonate/bicarbonate eluent solution designed for fast, accurate, and reproducible preparation of eluents for anion exchange chromatography. Formulated to a 100X concentration, this 250 mL solution eliminates the risk of operator error, potential contamination, and time-consuming manual preparation steps.
Optimized for use with Dionex™ IonPac™ AS22 columns, this high-purity eluent concentrate supports consistent chromatographic performance in routine anion analysis workflows, including environmental, industrial, and food & beverage testing.
Key Features
- Pre-formulated for convenience: Contains 0.45 M sodium carbonate and 0.14 M sodium bicarbonate in ultrapure deionized water
- Ready-to-dilute 100X concentrate: Simply dilute with ultrapure water to prepare working eluent
- High purity standards: Prepared with reagent-grade chemicals in 18.2 MΩ·cm deionized water
- Quality-verified: Concentration certified within ±2.5% accuracy by ion chromatography, UV spectrophotometry, titration, or gravimetric analysis
- Error-free preparation: Reduces lab-to-lab variability and risk of ionic contamination
- Compatible with IonPac™ AS22 columns: Ensures optimized eluent performance for anion separation
- Irritant classification: Handle with appropriate laboratory PPE
