Directed

From total allowable error via metrological traceability to uncertainty of measurement of the unbiarators and analytical specificity of the measurement procedure is stressed. The practicability of traceability to various levels and the advantages of the GUM approach for estimating uncertainty are shown.

Additive

Evaluation of measurement uncertainty for analytical procedures using a linear calibration functionhe complete calculation of measurement uncertainty including assessment of trueness is represented by an example concerning the determination of zinc in sediment samples using ICP-atomic emission spectrometry.

Analytical procedure in terms of measurement (quality) assurance,ment is stressed in view of specific inaccuracy sources such as sampling and matrix effects. And methods for their evaluation are outlined. The question of a clear criterion for analytical procedure validation is also addressed from the standpoint of the quality requirement which measurement results need to meet as an end-product.
