Determination of certain substances in electrotechnical products - Part 4: Mercury in polymers, metals and electronics by CV-AAS, CV-AFS, ICP-OES and ICP-MS
IEC 62321-4:2013 describes the use of four test methods for mercury in polymers, metals and electronics, namely CV-AAS (cold vapour atomic absorption spectrometry), CV-AFS (cold vapour atomic fluorescence spectrometry) ICP-OES (inductively coupled plasma optical emission spectrometry), and ICP-MS (inductively coupled plasma mass spectrometry) as well as several procedures for preparing the sample solution from which the most appropriate method of analysis can be selected by experts.

Détermination de certaines substances dans les produits électrotechniques - Partie 4: Mercure dans les polymères, métaux et produits électroniques par CV-AAS, CV-AFS, ICP-OES et ICP-MS
La CEI 62321-4:2013 décrit l'utilisation de quatre méthodes d'essai pour le mercure dans les polymères, à savoir CV-AAS (spectrométrie d'absorption atomique à vapeur froide), CV-AFS (spectrométrie de fluorescence atomique à vapeur froide, cold vapour atomic fluorescence spectrometry), ICP-OES (spectrométrie d'émission optique couplée à un plasma induit) et ICP-MS (spectrométrie de masse couplée à un plasma induit), ainsi que plusieurs procédures de préparation de la solution d'échantillon à partir de laquelle les experts peuvent choisir la méthode d'analyse la plus appropriée.
Določevanje posameznih snovi v elektrotehničnih izdelkih - 4. del: Določevanje živega srebra v polimerih, kovinah in elektroniki s CV-AAS, CV-AFS, ICP-OES in ICP-MS (IEC 62321-4:2013)
Standard 62321-4 opisuje preskusne metode za določanje živega srebra v polimerih, kovinah in elektroniki z metodami: atomska absorpcijska spektrometrija hladnih par (CV-AAS), atomska fluorescentna spektrometrija hladnih par (CV-AFS), optična emisijska spektrometrija z induktivno sklopljeno plazmo (ICP-OES) in masna spektrometrija z induktivno sklopljeno plazmo (ICP-MS). Ta standard opisuje določanje vsebnosti živega srebra (Hg) v elektrotehničnih izdelkih. Ti materiali so polimeri, kovine in elektronika (npr. plošče s tiskanim vezjem, hladnokatodne fluorescentne luči, živosrebrova stikala). Z baterijami, ki vsebujejo Hg, je treba ravnati, kot je opisano v [1]1. Medlaboratorijska študija je ocenila le te preskusne metode za plastiko. Druge matrice niso zajete. Ta standard se nanaša na vzorec kot predmet, ki se obdela in meri. Kaj ta vzorec je ali kako ga pridobiti, določa subjekt, ki izvaja preskuse. Dodatna navodila o pridobivanju reprezentativnih vzorcev iz končnih elektronskih izdelkov za testiranje ravni reguliranih snovi je mogoče najti v standardu IEC 62321-2. Opozoriti je treba, da lahko izbira in/ali določanje vzorca vpliva na razlago rezultatov preskusa. Ta standard opisuje uporabo štirih metod, in sicer CV-AAS (atomska absorpcijska spektrometrija hladnih par), CV-AFS (atomska fluorescentna spektrometrija hladnih par), ICP-OES (optična emisijska spektrometrija z induktivno sklopljeno plazmo) in ICP-MS (masna spektrometrija z induktivno sklopljeno plazmo), kot tudi več postopkov za pripravo vzorčne raztopine, s pomočjo katere lahko strokovnjaki izberejo najbolj primerno metodo analize. Analiza z metodami CV-AAS, CV-AFS, ICP-OES in ICP-MS omogoča določitev ciljnega elementa živega srebra z visoko natančnostjo (negotovost v nizkoodstotnem območju) in/ali visoko občutljivostjo (do ravni μg/kg). Testni postopki, opisani v tem standardu, so namenjeni zagotavljanju najvišje stopnje pravilnosti in natančnosti za vsebnosti živega srebra v območju od 4 mg/kg do 1000 mg/kg. Postopki se lahko uporabljajo tudi za višje koncentracije. Za neposredno analizo se lahko uporabi tudi toplotna razgradnja-amalgamiranje zlata v povezavi s CV-AAS (TD(G)-AAS) za analizo živega srebra brez prebave vzorca, čeprav so meje zaznavanja višje kot pri drugih postopkih zaradi zmanjšane velikosti vzorca.
