Results of chemical analyses are often used as a basis for important decisions and judgements (e.g. compliance or non-compliance of product or sample with a specification). The way the results of measurements are presented should make the decision making process easier for the end-user of the results. Therefore, in order to utilize correctly a result, it is necessary to take into account the measurement uncertainty. Measurement uncertainty, when evaluated correctly, gives a more realistic estimate of the true spread of results. Knowing the uncertainty, provides confidence to the analyst and the customer that decisions based on the results are being made with full knowledge of the range within which the true value lies.
