Fertilizers - Determination of sulfates content using three different methods

This document specifies three different methods (Methods A, B and C) for the determination of sulfur present in fertilizers extracts in the form of sulfates. Method A specifies the gravimetric method. Method B specifies the method using inductively coupled plasma optical spectrometry (ICP-OES). Method C specifies the method using ion chromatography (IC).

Düngemittel - Bestimmung von Sulfat mit drei verschiedenen Verfahren

Diese Europäische Norm legt drei verschiedene Verfahren (Verfahren A, B und C) für die Bestimmung des in Düngemittelextrakten vorliegenden Schwefels in Form von Sulfaten fest. Als Verfahren A ist das gravimetrische Verfahren festgelegt. Als Verfahren B ist die Bestimmung mittels optischer Emissionsspektro¬metrie mit induktiv gekoppeltem Plasma (ICP OES) festgelegt. Als Verfahren C ist die Vorgehensweise mittels Ionenchromatographie (IC) festgelegt.

Engrais - Dosage des sulfates selon trois méthodes différentes

La présente norme européenne spécifie trois méthodes différentes (méthodes A, B et C) de dosage du soufre présent dans les extraits d’engrais sous forme de sulfate. La méthode A utilise la gravimétrie. La méthode B emploie la spectrométrie d’émission optique à plasma inductif (ICP-OES). La méthode C a recours à la chromatographie ionique (IC).

Gnojila - Določevanje sulfatov s tremi različnimi metodami

Ta evropski standard opredeljuje tri različne metode (Metodo A, B in C) za določanje žvepla, prisotnega v ekstraktih gnojil v obliki sulfatov. Metoda A določa gravimetrično metodo. Metoda B določa metodo z uporabo optične spektrometrije z induktivno sklopljeno plazmo (ICP-OES). Metoda C določa metodo z uporabo ionske kromatografije (IC).
