For this, analysis of variance can be used as a statistical technique to derive standard uncertainties from homogeneity, stability and characterisation data.

Analytical procedure in terms of measurement (quality) assurance,lity of the measurement. A more sound definition of “analytical procedure” can be given in terms of measurement (quality) assurance, in which a specified procedure to be followed is explicitly associated with an established accuracy of the results produced. The logic and consequences of such an appr

Chemical metrology, chemistry and the uncertainty of chemical measurements,o be traceable back to the original sample. As a consequence, any useful estimation of uncertainty in results must include components arising from any lack of specificity of the method, the variation between repeats of the measurement and the relationship of the result to the original sample.

From total allowable error via metrological traceability to uncertainty of measurement of the unbiabias as well as random elements. Yet, to minimize diagnostic misclassifications, it is necessary to have spatio-temporal comparability of results. This requires trueness obtained through metrological traceability based on a calibration hierarchy. Hereby, the result is associated with a final uncerta
