In the paper, the methods of inter-laboratory QC that Calibration curve, standard sample, parallel samples and recovery test were used to evaluate the accuracy and precision of the analytical data. Study results: The calibration curve showed good linearity, correlation coefficient was 0.9999; The value of standard sample was accordant with the true value; The relative standard deviations of the determination was less than 6.1 %; The recovery rates of actual samples was 99.2 %~101 %; From the QC chart, we can see that all data were randomly distributed in both sides of the mean, without system deviation.
