The relative standard deviation (RSD) for the analysis of anions was less than 0.54% for the migration time and 1 to 4.25% for the peak area (n = 18). The detection limits were from 0.006 to 1.07 mg/L for the 11 anions (chloride, nitrate, sulfate, oxalate, tartrate, malate, succinate, citrate, phosphate, acetate, and lactate). This newly developed method is rapid, sensitive, and quantitative. Sample preparation is not time-consuming, and the method can be readily applied to food and beverage samples for quantitative analysis.
