9. IonPac Fast Anion III Anion-Exchange Column P111

10. The IonPac Fast Anion III 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 5 min. Anion: 阴离子 Hydroxide: 氢氧 化物，烃化物 Phosphoric: 磷 的，含磷的 Citric acid ： 柠檬酸

11. 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. Eluent ：洗提液 Generator ：发电机， 发生器 Reagent ：反 应力，反应物， 试剂 Ion chromatography ： 离子色谱 Deionized water: 去离子水 Potassium hydroxide: 氢氧化钾

12. RFIC systems ensure excellent peak area and retention time precision for phosphoric acid. The 3-mm i. d. configuration provides economical operation. i. d. ： inside diameter 内径 Peak area: 峰面 积 Retention time ： 保留时间

13. Eluent suppression using the ASRS® ULTRA II or AAES® provides RFIC suppressed conductivity detection with low backgrounds and enhanced analyte sensitivity. Anion Self-Regenerating Suppressor ： ASRS Anion Atlas ® Electrolytic Suppressor : AAES Conductivity ：传导 率，电导率 Analyte ：分析网

14. 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. Reproducible ： 可再生的 Compatible ： 相容的

15. 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 5 min using an isocratic potassium hydroxide eluent delivered by an eluent generator in combination with suppressed conductivity detection. Sonication ：超声 波降解法 Carbonation ：碳酸 饱和，碳酸化作用 Dilution ：稀释 Syrup ：糖浆 Recommend to ：交付 Isocratic potassium hydroxide eluent ：氢氧化钾等梯度洗脱 又称无梯度洗脱，恒溶剂洗脱。在色谱洗脱过程中流动相的组成保 持不变的洗脱方法。

16. The Fast Anion III 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 III Column is rugged and reliable and allows over 5,000 injections of cola samples with minimal column degradation. Peak area precision of <0.4% RSD and retention time precision of <0.15% RSD can be reliably obtained for phosphoric acid. potassium hydroxide eluent: 氢氧化钾洗脱液 Rugged ：崎岖不平的，多岩石的 RSD ：相对标准偏差

17. The Fast Anion III 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.
