Abstract
The simultaneous separation and determination of organic and inorganic acids were performed by capillary zone electrophoresis using indirect UV detection. 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.
