detection limit
Usage examples
  • In recent years plastic food contact materials are being developed that do not only consist of one plastic but combine up to 15 different plastic layers to attain optimum functionality and protection of the food, while reducing packaging waste. In such a plastic multi-layer material or article, layers may be separated from the food by a functional barrier. This barrier is a layer within food contact materials or articles preventing the migration of substances from behind that barrier into the food. Behind a functional barrier, non-authorised substances may be used, provided they fulfil certain criteria and their migration remains below a given detection limit.

LOD
  • antud mõõteprotseduuriga saadud suuruse mõõdis, mille korral eksliku väite tõenäosus, et komponent puudub materjalis on β, kui on antud tõenäosus α, mis ekslikult väidab komponendi olemasolu
  • measured quantity value, obtained by a given measurement procedure, for which the probability of falsely claiming the absence of a component in a materials is β, given a probability α of falsely claiming its presence

Usage examples
  • Avastamispiiri asemel ei ole soovitav kasutada terminit “tundlikkus”.
Good to know
  • IUPAC soovitab vaikimisi võtta α ja β väärtusteks 0,05.
