METHODS FOR EVALUATING THE UNCERTAINTY OF THE RESULTS OF DIRECT AND INDIRECT MEASUREMENTS OF ANALYTICAL VALUES
Journal Title: International scientific journal Science and Innovation - Year 2023, Vol 2, Issue 1
Abstract
Methods of estimating uncertainty of results of direct and indirect measurements of analytical values have been analysed. Analytical expressions for numerical calculation of main sources of physical and chemical values are given. Significant sources of measurement uncertainty have been simulated. The apparatus effects may include, for example, mistake limits of the analytical weights; The presence of a temperature regulator that can maintain an average temperature that differs (within specified limits) from the temperature recorded; Automatic analyzer, which can be subject to overload effects. Taking into account these specifics of analytical measurements, calculations of standardized standard uncertainties of measurement results according to GOST 1770 have been performed.
