(Main)Fertilizers - Determination of trace elements - Determination of mercury by vapour generation (VG) after aqua regia dissolution
Fertilizers - Determination of trace elements - Determination of mercury by vapour generation (VG) after aqua regia dissolution
This Technical Specification specifies a method for the determination of the content of mercury in fertilizers after extraction with aqua regia and the detection of mercury by vapour generation (VG) coupled to an atomic absorption spectrometer or an inductively coupled plasma atomic emission spectrometer. A limit of quantification of 0,01 mg/kg is to be expected.
Düngemittel - Bestimmung von Elementspuren - Bestimmung von Quecksilber mit Verdampfungstechnik (VG) nach Königswasseraufschluss
Diese Technische Spezifikation legt ein Verfahren zur Bestimmung von Quecksilber in Düngemitteln mittels Verdampfungstechnik (VG), gekoppelt mit Atomabsorptionsspektrometer oder Atomemissionsspektrometer mit induktiv gekoppeltem Plasma nach Königswasseraufschluss fest. Die Bestimmungsgrenze wird bei 0,01 mg/kg erwartet.
Engrais - Dosage des éléments traces - Détermination du mercure par génération de vapeur (VG) après digestion à l'eau régale
Cette spécification technique spécifie une méthode permettant de déterminer, après extraction à l’eau régale,
la teneur en mercure dans les engrais par détection de mercure par génération de vapeur (VG) couplée à un
spectromètre d’absorption atomique ou un spectromètre d’émission atomique avec plasma à couplage
inductif. Une limite de quantification de 0,01 mg/kg doit être attendue.
Gnojila - Določevanje elementov v sledovih - Določevanje živega srebra s tehniko hladnih par po raztapljanju v zlatotopki
Ta tehnična specifikacija določa metodo za določevanje vsebnosti živega srebra v gnojilih po ekstrakciji z zlatotopko in določevanje živega srebra s tehniko hladnih par (VG) z atomskim absorpcijskim spektrometrom ali atomskim emisijskim spektrometrom z induktivno sklopljeno plazmo. Pričakuje se meja kvantifikacije 0,01 mg/kg.

This Technical Specification (CEN/TS) was approved by CEN on 30 January 2012 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, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United Kingdom.
