ABSTRACT

The aim of this paper is to show the methodology of thedetermination of uncertainty related to the measurement of achemical quantity, using the law of propagation, through asimple example of glucose determination that shows the wayof identification, analysis and evaluation of the contributionof different components of uncertainty which are involved ina chemical measurement. Besides, the model of measurementand error concepts (systematic and random) are describedconceptually , in order to be able of distinguish them from theuncertainty concept.
