Estimation of uncertainty to the homogeneity study in the certification of a candidate certified reference material in fish matrix
Instituto de Pesquisas Energéticas e Nucleares – Ipen/CNEN-SP, Brazil
A homogeneity study in the preparation of a fish candidate certified reference material is reported. In the present study, homogeneity was examined by flow injection analysis cold vapour atomic absorption spectrometry technique (FIA-CV-AAS). Total mercury and methylmercury were studied in this study. Univariate analysis of variance (ANOVA) was performed for all analytes. The results were evaluated using an F-test, which demonstrated no significant difference for the between-bottle results. It is indicative that this material is homogeneous. The results of the between-bottle homogeneity study provide for the evaluation of one of the uncertainty components in the certification process.
