Objective:To organize the laboratory to participate in the CFAPA-2473 verification plan for the determination ability of sodium cyclohexylamine sulfonate in fruit juice to evaluate the laboratory's testing ability.Method:The samples were pre-treated according to the requirements of the test instructions,and the samples were determined by LC-MS/MS and gas chromatography.A variety of quality control methods were designed to evaluate the test results,such as parallel samples,standard addition and recovery,personnel comparison,instrument comparison,method comparison,and quality control samples.Result:The measurement result of CFAPA-2473 group A 150#sample is 0.099 6 g·kg-1,with a Z-value of 0.10;the measurement result of group B 180#sample is 0.322 g·kg-1,with a Z-value of 0.46.Conclusion:The absolute value of Z-value in both group A and group B is≤2,the laboratory test results were evaluated as satisfactory,indicating that the laboratory has the ability to determine sodium cyclohexylamine sulfonate.The quality control of the laboratory can operate effectively.
