Top down arsenic uncertainty measurement in water and sediments from Guarapiranga dam (Brazil)
2018 - FAUSTINO, M.G.; LANGE, C.N.; MONTEIRO, L.R.; FURUSAWA, H.A.; MARQUES, J.R.; STELLATO, T.B.; SOARES, S.M.V.; SILVA, T.B.S.C. da; SILVA, D.B. da; COTRIM, M.E.B.; PIRES, M.A.F.
Total arsenic measurements assessment regarding legal threshold demands more than average and standard deviation approach. In this way, analytical measurement uncertainty evaluation was conducted in order to comply with legal requirements and to allow the balance of arsenic in both water and sediment compartments. A top-down approach for measurement uncertainties was applied to evaluate arsenic concentrations in water and sediments from Guarapiranga dam (São Paulo, Brazil). Laboratory quality control and arsenic interlaboratory tests data were used in this approach to estimate the uncertainties associated with the methodology.
Control chart on semi analytical weighting
2018 - MIRANDA, G.S.; OLIVEIRA, C.C.; SILVA, T.B.S.C.; STELLATO, T.B.; MONTEIRO, L.R.; MARQUES, J.R.; FAUSTINO, M.G.; SOARES, S.M.V.; ULRICH, J.C.; PIRES, M.A.F.; COTRIM, M.E.B.
Semi-analytical balance verification intends to assess the balance performance using graphs that illustrate measurement dispersion, trough time, and to demonstrate measurements were performed in a reliable manner. This study presents internal quality control of a semianalytical balance (GEHAKA BG400) using control charts. From 2013 to 2016, 2 weight standards were monitored before any balance operation. This work intended to evaluate if any significant difference or bias were presented on weighting procedure over time, to check the generated data reliability. This work also exemplifies how control intervals are established.
