| Abstract: | In order to guarantee the quality of the analysis work,the uncertainty for the measurement of trace Sm in solution by ICP-MS was expressed in internationally current ways.All the parameters needed for the calculation were collected and calculated.The standard uncertainty,combined standard uncertainty,degrees of freedom and expanded uncertainty were evaluated.This method can also be applied to the uncertainty evaluation for the determination results of other similar instruments. |
