 David Brynn Hibbert

David Brynn Hibbert, also known as Brynn Hibbert, is an analytical chemistry researcher whose work combines chemometrics, electrochemical measurements and metrological traceability. His university profile records his tenure in the UNSW analytical-chemistry chair from1987 to2013 and his editorship of the IUPAC terminology compendium known as the Orange Book. The Royal Society of New South Wales explicitly verifies his full name.^[ref]

With Paul De Bièvre, René Dybkær and Aleš Fajgelj, David Brynn Hibbert coauthored the IUPAC report on the concepts and implementation of metrological traceability in chemical measurement. Its goal was a consistent account of how a result is related to a reference, including the concepts needed to communicate that relationship.^[ref]

An original illustration explains the value of a measurement model in chemometrics. Suppose two ideal sensors give $x_1=c+b$ and $x_2=c-b$, where $c$ is the target concentration and $b$ an interfering response. Their mean recovers $c$, while their difference diagnoses $2b$. If both instead respond as $c+b$, averaging cannot remove the interference. The chemical response model determines what additional measurements identify; having more numbers alone does not guarantee more independent information.
