Plant biostimulants - Determination of inorganic arsenic
This document specifies a method for extraction, separation, and determination of inorganic arsenic (iAs) in plant biostimulants using anion-exchange high performance liquid chromatography (HPLC) or ion chromatography (IC) coupled to ICP-MS. This document is 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).
Pflanzen-Biostimulanzien - Bestimmung von anorganischem Arsen
Dieses Dokument legt ein Verfahren zur Extraktion, Trennung und Bestimmung von anorganischem Arsen in Pflanzen-Biostimulanzien mit Anionenaustausch-Hochleistungs-Flüssigchromatograph (HPLC) oder Ionen¬chromatographie (IC) gekoppelt mit ICP MS fest. Dieses Dokument ist 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.
Biostimulants des végétaux - Dosage de l'arsenic inorganique
Le présent document spécifie une méthode d’extraction, de séparation et de dosage de l’arsenic inorganique (iAs) dans les biostimulants des végétaux par chromatographie en phase liquide haute performance (HPLC) avec échange d’anions ou par chromatographie ionique (IC) couplée à une ICP-MS. Le présent document est 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 % le plus élevé en masse dans le 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.
