Objectives To explore the application of the quality control graph of the determination of standard reference material and international intercalibration study in quality control by the analysis of our la-boratory’s results from interlaboratory comparison with trace elements in foods in October 2013. Methods Z-scores were used to appraise the results from the interlaboratory comparison with trace elements in foods organized by International Atomic Energy Agency, and analyzed the determination of the concentrations of trace elements in foods. Results The absolute values of Z-score of concentrations of almost trace elements determined by our laboratory were less than 1, indicating results were excellent. Conclusion The quality control graph and international intercalibration study is a greatly effectively approach of quality control.
