Nanotechnologies - Analysis of nano-objects using asymmetrical-flow and centrifugal field-flow fractionation (ISO/TS 21362:2018)

This document identifies parameters and conditions, as part of an integrated measurement system, necessary to develop and validate methods for the application of asymmetrical-flow and centrifugal field-flow fractionation to the analysis of nano-objects and their aggregates and agglomerates dispersed in aqueous media. In addition to constituent fractionation, analysis can include size, size distribution, concentration and material identification using one or more suitable detectors. General guidelines and procedures are provided for application, and minimal reporting requirements necessary to reproduce a method and to convey critical aspects are specified.

Nanotechnologien - Analyse von Nanoobjekten mit Hilfe von Asymmetrischer-Fluss-Feldflussfraktionierung und zentrifugaler Feldflussfraktionierung (ISO/TS 21362:2018)

Dieses Dokument identifiziert als Teil eines integrierten Messsystems Parameter und Bedingungen, die zur Entwicklung und Validierung von Methoden für die Anwendung der Asymmetrischer-Fluss-Feldflussfraktionierung und zentrifugaler Feldflussfraktionierung zur Analyse von Nanoobjekten und ihren in wässrigen Medien dispergierten Aggregaten und Agglomeraten erforderlich sind. Zusätzlich zur Fraktionierung der Bestandteile kann die Analyse die Größe, Größenverteilung, Konzentration und Materialidentifizierung mit einem oder mehreren geeigneten Detektoren umfassen. Für die Anwendung werden allgemeine Anleitungen und Verfahren bereitgestellt, und es werden Mindestanforderungen an die Berichterstattung festgelegt, die zur Reproduzierung einer Methode und zur Vermittlung kritischer Aspekte erforderlich sind.

Nanotechnologies - Analyse des nano-objets par fractionnement par couplage flux-force asymétrique et à force centrifuge (ISO/TS 21362:2018)

Le présent document identifie, dans le cadre d'un système de mesures intégrées, les paramètres et conditions nécessaires au développement et à la validation de méthodes pour l'application des systèmes de fractionnement par couplage flux-force asymétrique et à force centrifuge à l'analyse de nano-objets et de leurs agrégats et agglomérats en dispersion dans des milieux aqueux. Outre le fractionnement des composants, l'analyse peut porter sur la taille, la distribution granulométrique, la concentration et l'identification des matériaux à l'aide d'un ou plusieurs détecteurs appropriés. Le présent document fournit des lignes directrices et procédures générales pour l'application et spécifie les exigences de rapport minimales afin de reproduire une méthode et de rendre compte des aspects critiques.
