Summary: La présente Norme européenne spécifie une méthode de dosage du mercure dans les aliments des animaux par spectrométrie d’absorption atomique à vapeur froide (SAAVF) après digestion sous pression par micro-ondes. Il convient que la limite de quantification dans la solution d’essai soit inférieure ou égale à 0,25 µg/l. En utilisant une prise d’essai de 0,5 g et un volume de solution d’essai de 25 ml, il convient d’obtenir une limite de quantification inférieure ou égale à 0,0125 mg/kg.

This European Standard specifies a method for the determination of mercury in animal feeding stuffs by Cold-Vapour Atomic Absorption Spectrometry (CVAAS) after microwave pressure digestion. The limit of quantification in the test solution should be 0,25 µg/l or lower. Using a test portion of 0,5 g and a volume of the test solution of 25 ml a limit of quantification of 0,0125 mg/kg or lower should be obtained.

Diese Europäische Norm legt ein Verfahren für die Bestimmung von Quecksilber in Futtermitteln nach Druckaufschluss in einem Mikrowellengerät mit Kaltdampf-Atomabsorptionsspektrometrie (KD-AAS) fest. Die Bestimmungsgrenze in der Prüflösung sollte ≤ 0,25 µg/l sein. Mit einer Prüfmenge von 0,5 g und einem Volumen der Prüflösung von 25 ml sollte eine Bestimmungsgrenze von 0,012 5 mg/kg erlangt werden.
