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 fertilizer 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

Dieses Dokument legt drei verschiedene Verfahren (Verfahren A, B und C) für die Bestimmung des in Dünge¬mittelextrakten vorliegenden Schwefels in Form von Sulfaten fest. Als Verfahren A ist das gravimetrische Verfahren festgelegt. Als Verfahren B ist die Bestimmung mittels optischer Emissionsspektrometrie mit induktiv gekoppeltem Plasma (ICP OES) festgelegt. Als Verfahren C ist die Vorgehensweise mittels Ionen¬chromatographie (IC) festgelegt.

Engrais - Dosage des sulfates selon trois méthodes différentes

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

Gnojila - Določevanje sulfatov s tremi različnimi metodami

Ta evropski standard določa metodo za določevanje količine izboljševalcev tal, razen materialov za apnenje in rastnih substratov v razsutem in zapakiranem stanju. Ta dokument se uporablja za material v trdni obliki, vendar ne v obliki blokov, ki se prodaja po dimenzijah, in ki presega omejitev velikosti delcev v standardu EN 12580 ter kjer je deklarirana nazivna velikost delcev večja od 60 mm.
