| | | IonPac Fast Anion IIIA Anion-Exchange Column |  | The IonPac Fast Anion IIIA hydroxide-selective, anion-exchange column is specifically designed for the determination of phosphoric and citric acids in cola soft drinks. Its capacity and selectivity allows for the rapid analysis of these acids in less than 7 min. Recommended column for fast analysis of phosphoric and citric acids in cola soft drinks. Use with the eluent generator of a Reagent-FreeTM Ion Chromatography (RFICTM) system for simplified operation. Requires only a deionized water source to produce potassium hydroxide eluent. RFIC systems ensure excellent peak area and retention time precision for phosphoric acid. The 3-mm i.d. configuration provides economical operation. Eluent suppression using the ASRS® 300 or AAES® provides RFIC suppressed conductivity detection with low backgrounds and enhanced analyte sensitivity. Column selectivity is optimized for a 30 °C operating temperature to ensure reproducible retention times in all environmental conditions. Compatible with organic solvents to enhance analyte solubility, modify column selectivity, or allow effective column cleanup.
The cola samples may require sample pretreatment with sonication to remove carbonation. Sample dilution of cola syrups is recommended prior to analysis to ensure optimum column life. These acids can be analyzed in less than 7 min using an isocratic potassium hydroxide eluent delivered by an eluent generator in combination with suppressed conductivity detection. The Fast Anion IIIA Column is recommended for use with RFIC systems with eluent generation (RFIC-EGTM systems) that require only a deionized water source to produce potassium hydroxide eluent. The Fast Anion IIIA Column is rugged and reliable for the determination of phosphoric and citric acids in cola soft drinks. The Fast Anion IIIA Column is ideally used with RFIC technology for automatic eluent generation. Use the Anion Self-Regenerating Suppressor (ASRS 300, 2 mm) or the Anion Atlas Electrolytic Suppressor (AAES) with the Fast Anion IIIA Column for eluent suppression.
