Uncertainty of Analytic Measurements: Classical and New Approaches to Estimation

Resumo

A comparative analysis of the results of estimation of measurement uncertainty is conducted. The results are obtained by a method described in the Handbook on the Expression of Uncertainty in Measurement and also by Monte-Carlo methods and empirical and Bayesian methods recommended in a tentative version of the Handbook. Examples of calculations of measurement uncertainty for several measurement techniques in the field of analytic chemistry are presented. Features of the application and the advantages and drawbacks of the methods are described.
