A simple, selective, and precise reversed-phase HPLC method has been developed for the simultaneous quantification of acesulfame-K, saccharin, aspartame, caffeine and benzoic acid in no-added sugar cola soft drinks. The chromatographic separation was performed by using potassium dihydrogen orthophosphate buffer (pH = 4.3) and acetonitrile (88:12, v/v) as mobile phase, a DS Hypersil C 18.5 μm column (250 mm ± 4.6 mm) and "diode array" detection at λ= 227 nm for acesulfame-K, λ= 265 nm for saccharin and λ= 217 nm for aspartame, caffeine and benzoic acid. The analysis time was less than 40 min. The calibration curves showed good linearity over the concentration range of 0-100 mg/L. The validation of the analysis method was attempted in terms of sensitivity, linearity range, reproducibility, repeatability, analytical recovery and robustness.
