Foodstuffs - Determination of trace elements - Determination of sodium and magnesium by flame atomic absorption spectrometry (AAS) after microwave digestion

This document specifies methods for the determination of sodium and magnesium in foodstuffs by flame atomic absorption spectrometry (AAS) after microwave digestion. Collaborative studies have been carried out (Annex A). The method is suitable for the determination of sodium not less than 1 500 mg/kg and magnesium not less than 250 mg/kg. Data for calcium is included for information (Annex B). The method is not applicable to wheat bran.

Lebensmittel - Bestimmung von Elementspuren - Bestimmung von Natrium und Magnesium mit Flammen-Atomabsorptionsspektrometrie (AAS) nach Mikrowellenaufschluss

Dieses Dokument legt Verfahren zur Bestimmung von Natrium und Magnesium in Lebensmitteln mit
Flammen-Atomabsorptionsspektrometrie (AAS) nach Mikrowellenaufschluss fest. Ringversuche wurden
durchgeführt (Anhang A). Das Verfahren ist für die Bestimmung von Natrium bei einer Konzentration von
mindestens 1 500 mg/kg Trockensubstanz und Magnesium von mindestens 250 mg/kg Trockensubstanz
geeignet. Zur Information sind Daten für Calcium enthalten (Anhang B). Das Verfahren ist nicht auf
Weizenkleie anwendbar.

Produits alimentaires - Dosage des éléments traces - Dosage du sodium et du magnésium par spectrométrie d'absorption atomique de flamme après digestion par micro-ondes

Le présent document prescrit des méthodes de dosage du sodium et du magnésium dans les produits
alimentaires par spectrométrie d’absorption atomique de flamme après digestion par micro-ondes. Des études
conjointes ont été réalisées (Annexe A). La méthode convient pour le dosage du sodium et du magnésium,
avec une teneur respective en matière sèche au moins égale à 1 500 mg/kg et 250 mg/kg. Les données
concernant le calcium sont incluses pour information (Annexe B). La méthode n’est pas applicable au son de
blé.
