Animal feeding stuffs - Determination of inorganic arsenic by hydride generation atomic absorption spectrometry (HG-AAS) after microwave extraction and separation by solid phase extraction (SPE)

Edition date: 2023-09-03
In Force
Summary: Diese Europäische Norm beschreibt ein Verfahren für die Bestimmung von anorganischem Arsen in Futtermitteln marinen Ursprungs mittels Festphasenextraktion (SPE) (en: Solid Phase Extraction) und der Atomabsorptionsspektrometrie-Hydridtechnik (HD AAS). Das Verfahren wurde in einem Ringversuch erfolgreich mit einem Messbereich von 0,19 mg/kg bis 2,7 mg/kg (HORRAT-Werte < 2; der HORRAT-Wert ist der Horwitz-Ratio-Wert) geprüft. Die Bestimmungsgrenze LOQ (en: Limit Of Quantification) des Verfahrens beträgt im Allgemeinen etwa 0,1 mg/kg oder weniger.

This European Standard describes a procedure for the determination of inorganic arsenic in animal feeding stuffs of marine origin by Solid Phase Extraction (SPE) and Hydride Generation Atomic Absorption Spectrometry (HG-AAS). The method has been successfully tested in a collaborative trial with a working range from 0,19 mg/kg to 2,7 mg/kg (HORRATvalues < 2). The LOQ of the method is usually approximately 0,1 mg/kg or lower.

La présente Norme européenne décrit un mode opératoire de dosage de l’arsenic inorganique dans les aliments des animaux d’origine marine par extraction en phase solide (SPE) et par spectrométrie d’absorption atomique par génération d'hydrures (SAA-GH). La méthode a passé avec succès un essai interlaboratoires avec une plage de travail comprise entre 0,19 mg/kg et 2,7 mg/kg (valeurs HORRAT < 2 ; la valeur HORRAT est la valeur du rapport de Horwitz). La LOQ de la méthode est habituellement d’environ 0,1 mg/kg ou moins.
