Food authenticity - Determination of C and/or N isotope ratios in food by Elemental Analyser - Isotope Ratio Mass Spectrometry (EA-IRMS)
This document covers instrumental analysis by elemental analyser-isotope ratio mass spectrometry (EA-IRMS) of food materials to determine C and/or N isotope ratios.
The isotope ratios obtained by following this document are expressed as δ13C and/or δ15N values relative to international measurement standards.
Sample preparation is not included within this document. It is assumed that the food sample has been pre-treated as necessary and homogenized.
Similarly, the interpretation of the obtained isotope delta values is not covered by this document. Following this protocol will result only in isotope delta values for the sample materials.
Solid and/or liquid sample materials can be analysed following this document.
Although other instrumental techniques can be applied to determine δ13C and/or δ15N values in food materials, these other techniques are not covered by this document.
Lebensmittelauthentizität - Bestimmung von C- und/oder N-Isotopenverhältnissen in Lebensmitteln mittels Elementaranalyse mit Isotopenverhältnis-Massenspektrometrie (EA‑IRMS)
Dieses Dokument behandelt die instrumentelle Analyse von Lebensmitteln mittels Elementaranalysator und einem Isotopenverhältnis-Massenspektrometer (EA-IRMS) zur Bestimmung des C- und/oder N-Isotopenverhältnisses.
Die nach diesem Dokument ermittelten Isotopenverhältnisse werden als δ13C und/oder δ15N-Werte relativ zu internationalen Messnormalen ausgedrückt.
Die Probenvorbereitung ist in diesem Dokument nicht enthalten. Es wird davon ausgegangen, dass die Lebensmittelprobe wie erforderlich vorbehandelt und homogenisiert wurde.
Auch die Auswertung der erhaltenen Isotopen-Delta-Werte wird in diesem Dokument nicht behandelt. Die Anwendung dieses Protokolls führt nur zu Isotopen-Delta-Werten für die Probenmaterialien.
Es können feste und/oder flüssige Probenmaterialien nach diesem Dokument analysiert werden.
Obwohl auch andere instrumentelle Techniken zur Bestimmung von δ13C- und/oder δ15N-Werten in Lebensmitteln angewendet werden können, werden diese anderen Techniken von diesem Dokument nicht abgedeckt.
Authenticité des aliments - Détermination des rapports isotopiques du carbone et/ou de l’azote dans les aliments au moyen d’un analyseur élémentaire couplé à un spectromètre de masse de rapports isotopiques (AE-SMRI)
Le présent document concerne l’analyse instrumentale de produits alimentaires, au moyen d'un analyseur élémentaire couplé à un spectromètre de masse de rapports isotopiques (AE-SMRI), pour déterminer les rapports isotopiques du carbone et/ou de l’azote.
Les rapports isotopiques obtenus conformément au présent document sont exprimés en valeurs δ13C et/ou δ15N en fonction d’étalons de mesure internationaux.
La préparation des échantillons ne figure pas dans le présent document. On suppose que l’échantillon d’aliment a été traité si nécessaire, et homogénéisé.
De la même façon, l’interprétation des valeurs du delta isotopique obtenues n’est pas abordée par le présent document. La mise en oeuvre de ce protocole fournira uniquement des valeurs du delta isotopique pour les échantillons.
Les échantillons solides et/ou liquides peuvent être analysés conformément au présent document.
Bien que d’autres techniques instrumentales puissent être appliquées pour déterminer les valeurs δ13C et/ou δ15N dans les échantillons, ces autres techniques ne sont pas abordées par le présent document.
