Plant biostimulants - Determination of specific elements - Part 1: Digestion by aqua regia for subsequent determination of elements

This document specifies the method for the digestion of different plant biostimulants with aqua regia to enable a subsequent determination of arsenic (As), cadmium (Cd), copper (Cu), chromium (Cr), mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn). The method can be also applied for determination of other elements. The method is applicable for all solid and/or liquid plant biostimulants.
This document is also applicable to the fertilizing product blends belonging to PFC 7 where the EU fertilising product plant biostimulant contained in the blend represents the highest % by mass in the blend. In case of equal shares, the user can apply either this or the standard(s) applicable to the other component product(s).
The extracts are suitable for analysis using EN 17701 2:—  (ICP-AES) and EN 17701 3:—  (Hg analysis).
NOTE   Alternatively, inductively coupled plasma mass spectrometry (ICP-MS) can be used for the determination of the elements in the aqua regia digests if the user proves that the method gives the same results.

Pflanzen-Biostimulanzien - Bestimmung spezifischer Elemente - Teil 1: Aufschluss durch Königswasser zur anschließenden Bestimmung der Elemente

Dieses Dokument legt das Verfahren für den Aufschluss verschiedener Pflanzen-Biostimulanzien mit Königs¬wasser fest, um eine anschließende Bestimmung von Arsen (As), Cadmium (Cd), Kupfer (Cu), Chrom (Cr), Quecksilber (Hg), Nickel (Ni), Blei (Pb) und Zink (Zn) zu ermöglichen. Das Verfahren kann auch für die Bestimmung anderer Elemente verwendet werden. Das Verfahren ist für alle festen und/oder flüssigen Pflanzen-Biostimulanzien anwendbar.
Dieses Dokument ist auch für Düngeproduktmischungen anwendbar, die zur PFC 7 gehören und bei denen das in der Mischung enthaltene EU Düngeprodukt Pflanzen-Biostimulans den größten Massenanteil in % in der Mischung ausmacht. Im Fall von gleich großen Anteilen kann der Anwender entweder die vorliegende Norm oder die für den/die anderen Bestandteil(e) anwendbare(n) Norm(en) verwenden.
Die Extrakte sind für die Analyse nach EN 17701 2:—  (ICP AES) und EN 17701 3:—  (Quecksilber-Analyse) geeignet.
ANMERKUNG   Alternativ kann die Massenspektrometrie mit induktiv gekoppeltem Plasma (ICP MS) für die Bestimmung der Elemente in den Königswasseraufschlüssen genutzt werden, sofern der Anwender nachweist, dass das Verfahren zu den gleichen Ergebnissen führt.

Biostimulants des végétaux - Dosage des éléments spécifiques - Partie 1 : Digestion à l’eau régale pour le dosage ultérieur des éléments

Le présent document spécifie la méthode pour la digestion de différents biostimulants des végétaux à l’eau régale pour permettre le dosage ultérieur de l’arsenic (As), du cadmium (Cd), du cuivre (Cu), du chrome (Cr), du mercure (Hg), du nickel (Ni), du plomb (Pb) et du zinc (Zn). Cette méthode peut aussi être appliquée pour le dosage d’autres éléments. La méthode est applicable à tous les biostimulants des végétaux solides et/ou liquides.
Le présent document est également applicable aux mélanges de fertilisants appartenant à la catégorie PFC 7, dans lesquels le fertilisant UE biostimulant des végétaux contenu dans le mélange représente le plus fort % en masse du mélange. Dans le cas où les proportions sont égales, l’utilisateur peut appliquer la présente norme ou la ou les normes applicables aux autres produits constituants.
Les extraits conviennent pour une analyse selon l’EN 17701 2:—  (ICP-AES) et l’EN 17701 3:—  (analyse du Hg).
NOTE   Il est également possible d’utiliser la spectrométrie de masse avec plasma à couplage inductif (ICP-MS) pour le dosage des éléments dans les digestats à l’eau régale, si l’utilisateur prouve que la méthode conduit aux mêmes résultats.
