| Abstract: | In this paper, the HG-AFS derivation is presented for the evaluation of uncertainty to determine arsenic content of milk powder. Various sources of uncertainty from the determination procedure are assessed. The influence of the identified uncertainty of the analytical result is evaluated, and references for the reliability and consistency of the testing date in the laboratory are made. |
