dcterms:description
The postulated uncertainty of many commercially available standard solutions is estimated on the basis of uncertainties of individual preparation steps. The declared concentration of Cu standard solution (1000 +/- 2) mg/L was verified by gravimetric analysis (found (1000.7 +/- 0.4) mg/L), isotope dilution with commercial and laboratory-prepared isotope-enriched solutions (found (1000.6 +/- 16.8) mg/L and (1002.4 +/- 3.6) mg/L, respectively), and by atomic absorption spectrometry (found (1001.4 +/- 5.3) mg/L). Uncertainty budgets of all used methods are given and the procedures of uncertainty estimation are fully documented.
