| Abstract: | In the paper,the constructed mathematical models,together with choose assessment method,were used to analysis the main source of measurement uncertainty of Pb and Cd measured by ICP-MS,after analyzing and synthesizing of six components,the samples weighing,digestion,the volume size,determination of the standard process of preparation,curve fitting,equipment measurement repeatability in the process of anglicizing,the expanded uncertainty of Pb and Cd was calculated. These data provided references for the rel... |
