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 also applicable to the blends of fertilizing products where plant biostimulants are the main part of the blend. Otherwise, the Technical Specification for the main part of the blend applies.

Pflanzen-Biostimulanzien - Bestimmung von anorganischem Arsen

Dieses Dokument legt ein Verfahren zur Extraktion, Trennung und Bestimmung von anorganischem Arsen in Planzen-Biostimulanzien mit Anionenaustausch Hochleistungs-Flüssigchromatograph (HPLC) oder Ionenchromatographie (IC) gekoppelt mit ICP MS fest.
Dieses Dokument ist auch anzuwenden für die Mischungen von Düngeprodukten, in denen die Planzen-Biostimulanzien der Hauptbestandteil der Mischung sind. Andernfalls ist die Technische Spezifikation für den Hauptbestandteil der Mischung anzuwenden.

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 liquide haute performance (HPLC) ou chromatographie ionique (IC) couplée à une ICP-MS.
Le présent document est également applicable aux mélanges de fertilisants dans lesquels les biostimulants des végétaux représentent la majorité du mélange. Dans le cas contraire, c’est la Spécification technique correspondant au fertilisant majoritairement présent dans le mélange qui s’applique.

Rastlinski biostimulanti - Določevanje anorganskega arzena

Ta dokument določa metodo za ekstrakcijo, ločevanje in določevanje anorganskega arzena (iAs) v rastlinskih biostimulantih z anionsko izmenjavo HPLC ali IC v povezavi z masno spektrometrijo z induktivno sklopljeno plazmo (ICP-MS).
Dokument je uporaben tudi za mešanice sredstev za gnojenje, pri katerih so rastlinski biostimulanti glavni del mešanice. V nasprotnem primeru se uporablja tehnična specifikacija za glavni del mešanice.

This Technical Specification (CEN/TS) was approved by CEN on 3 January 2022 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and
