Animal feeding stuffs: Methods of sampling and analysis - Determination of iodine in animal feed by ICP-MS
This European standard specifies a method for the determination of iodine in animal feeding stuffs by inductively coupled plasma mass spectrometry (ICP-MS) following extraction with an alkaline solution.
This method was successfully tested in the range of 0,70 to 631 mg/kg in following animal feeds: seaweed meal, mineral premixture, fish meal, plant based ingredient, marine based compound feed and a synthetic iodine solution.
Futtermittel - Probenahme- und Untersuchungs-verfahren - Bestimmung von Iod in Futtermitteln mittels Anionenaustausch ICP-MS
Diese Europäische Norm legt ein Verfahren zur Bestimmung von Iod in Futtermitteln mit der Massenspektrometrie und induktiv gekoppeltem Plasma (ICP-MS) nach dessen Extraktion mit einer alkalischen Lösung fest.
Dieses Verfahren wurde im Bereich von 0,70 mg/kg bis 631 mg/kg in folgenden Futtermitteln angewendet: Seealgenmehl, Mineralstoffvormischung, Fischmehl, pflanzlicher Wirkstoff, Mischfutter aus Meerestieren und eine synthetische Iodlösung.
Aliments des animaux - Méthodes d’échantillonnage et d’analyse - Dosage de l’iode dans les aliments pour animaux par spectrométrie de masse à plasma induit par haute fréquence (ICP-MS)
La présente Norme européenne spécifie une méthode de dosage de l’iode dans les aliments des animaux par spectrométrie de masse à plasma induit par haute fréquence (ICP-MS) après extraction avec une solution alcaline.
Cette méthode a été soumise à essai avec succès dans la plage de 0,70 mg/kg à 631 mg/kg avec les aliments des animaux suivants : farine d’algue, prémélange minéral, farine de poisson, ingrédient à base de plante, aliments composés d’origine marine et une solution d’iode synthétique.
Krma: metode vzorčenja in analize - Določevanje joda v krmi z masno spektrometrijo z induktivno sklopljeno plazmo (ICP-MS)
Ta evropski standard določa metodo za določevanje joda v krmi z masno spektrometrijo z induktivno sklopljeno plazmo (ICP-MS) po ekstrakciji z alkalno raztopino.
Ta metoda je bila uspešno preskušena v razponu od 0,70 do 631 mg/kg pri naslednjih vrstah krme: moka iz morskih alg, mineralni premiks, ribja moka, rastlinska sestavina, morska krmna mešanica in sintetična raztopina joda.
