| Abstract: | The determination of bromate in drinking water samples has been carried out by ion chromatography and the uncertainty of the measurement results has been evaluated. The main sources that affect the uncertainty of measurement have beem analyzed. The factors that affect the uncertainty of the standard reserve solution, such as the dilution of standard solution, the standard curve fitting, the sample repeatability measurement and the instrument have been analyzed. The expansion inaccuracy has been calculated. It makes the result more objective and true, and provide references for laboratory quality control. |
