However, in terms of uncertainty evaluation the very small levels of flow entail problems characterized by a \u201cclose to the physical limit\u201d situation. The same happens in nanovolume applications. In these cases the Law of Propagation of Uncertainty framework (GUM) may not to be adequate, since the interval of coverage probability will, in some circumstances, contain negative values, which is physically difficult to explain. Monte Carlo methods may be a good alternative when there are not many negative readings in the application (limit-of-detection problem), but may also prove inadequate otherwise, since the required functional relationship of the model will produce a peak of values centred at the zero value, which is also not very credible to describe satisfactorily the real situation. In the latter, the application of a Bayesian method will be the better approach to deal with the evaluation of measurement uncertainties. The whole process of the revision of the international metrological standardization lies in this principle, of selecting the best method to tackle the particular problem in hand, and not to apply blind recipes to the evaluation of uncertainty in measurement, and there is a new EMPIR project focused on providing examples to BIPM documents to strengthen this concept.<\/jats:p>","DOI":"10.1088\/1742-6596\/1379\/1\/012033","type":"journal-article","created":{"date-parts":[[2019,11,29]],"date-time":"2019-11-29T22:13:15Z","timestamp":1575065595000},"page":"012033","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Method selection to evaluate measurement uncertainty in microflow applications"],"prefix":"10.1088","volume":"1379","author":[{"given":"J A","family":"Sousa","sequence":"first","affiliation":[]},{"given":"E","family":"Batista","sequence":"additional","affiliation":[]},{"given":"O","family":"Pellegrino","sequence":"additional","affiliation":[]},{"given":"A S","family":"Ribeiro","sequence":"additional","affiliation":[]},{"given":"L L","family":"Martins","sequence":"additional","affiliation":[]}],"member":"266","reference":[{"key":"JPCS_1379_1_012033bib1"},{"key":"JPCS_1379_1_012033bib2"},{"key":"JPCS_1379_1_012033bib3"},{"key":"JPCS_1379_1_012033bib4","first-page":"S16","article-title":"Analysis of infusion pump error logs and their significance for health care","author":"Lee","year":"2012"},{"key":"JPCS_1379_1_012033bib5","doi-asserted-by":"crossref","first-page":"716","DOI":"10.2337\/dc15-0168","article-title":"Insulin pump risks and benefits: a clinical appraisal of pump safety standards, adverse event reporting, and research needs: a joint statement of the European Association for the Study of Diabetes and the American Diabetes Association Diabetes Technology Working Group","volume":"38","author":"Heinemann","year":"2015","journal-title":"Diabetes Care"},{"key":"JPCS_1379_1_012033bib6","doi-asserted-by":"crossref","first-page":"78","DOI":"10.1111\/j.1460-9592.2010.03475.x","article-title":"Quantitative analysis of continuous intravenous infusions in pediatric anesthesia: Safety implications of dead volume, flow rates, and fluid delivery","volume":"21","author":"Ma","year":"2011","journal-title":"Paediatr.
