PROBLEM TO BE SOLVED: To simultaneously analyze chloride ions, phosphate ions and sulfate ions in a sample, in which organic acids coexist, such as wine, by separating them from sulfurous acid ions and organic acid ions. SOLUTION: In a method for simultaneous analysis, the chloride ions, phosphate ions and sulfate ions in wine are separated from sulfurous acid ions and organic acid ions by ion chromatography, using a moving phase to which a carbonyl compound, such as acetone, is added.
