Objective To evaluate the uncertainty of the determination of acesulfame in red wine by high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS). Methods The evaluation model was established according to SN/T 3538-2013 Determination of six kinds of artificial sweeteners in foodstuffs for export-LC-MS/MS method. The main sources of uncertainty resulted from the determination process were discussed and calculated to get the composite uncertainty and extended uncertainty. Results When the acesulfame content was 0.968 mg/kg in red wine, its extended relative uncertainty was 0.0616 mg/kg (P=95%, k=2). Conclusion The uncertainties of the experiments are mainly derived from the recovery rate, repeatability tests and preparation of standard solutions.
