We used an IC SI-90 4E, a column for anion analysis, to analyze seven standard anions (F^-, Cl^-, NO₂^-, Br^-, NO₃^-, HPO₄^2-, SO₄^2-). The use of an eluent with aqueous solution of 1.8 mM Na₂CO₃ + 1.7 mM NaHCO₃ is best suited to the separation of those seven anions. A good separation of seven ions and carbonate ion was achieved even at 2.0 mL/min flow rate, demonstrating the method’s suitability for a rapid analysis.
