Annotation of standard text ÖNORM EN 18054 :

Dieses Dokument legt ein Verfahren für die instrumentelle Analyse von Lebensmitteln mittels Elementaranalysator und einem Isotopenverhältnis-Massenspektrometer (EA-IRMS) zur Bestimmung des C- und/oder N-Isotopenverhältnisses fest. Die nach diesem Dokument ermittelten Isotopenverhältnisse werden als d13C und/oder d15N-Werte relativ zu internationalen Messnormalen ausgedrückt. Dieses Dokument ist nicht für die Probenvorbereitung anwendbar. Es wird davon ausgegangen, dass die Lebensmittelprobe wie erforderlich vorbehandelt und homogenisiert wurde. Auch die Interpretation 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 d13C- und/oder d15N-Werten in Lebensmitteln angewendet werden können, werden diese anderen Techniken von diesem Dokument nicht abgedeckt. Beim Kauf dieser ÖNORM EN steht zusätzlich zum Dokumentinhalt auch eine kostenfreie digitale Zusatzdatei vorhanden (xlsx-Datei mit Beispielen für die Datenverarbeitung) zur Verfügung.
