BS PD CEN/TS 17273:2018规定了复杂基质的取样和处理要求，以获得 具有足够高浓度的感兴趣纳米物体的液体分散体。本文件为复杂环境中特定纳米物体的检测和识别提供了指南 基质，如液体环境隔室、废水和消费品（如食品、， 化妆品）。本文件要求识别纳米物体性质的先验知识 比如它们的化学成分。选择的检测和识别方法基于 粒度分类和化学成分分析的结合。 身份也可以是 支持，例如通过额外的形态表征。目前只有现场流动分馏， 电子显微镜和单粒子电感耦合等离子体质谱技术满足了这一要求 组合条件。交叉引用:ISO 13322-1ISO 9276-2ISO/DIS 21363ISO 9276-6ISO 9276-4ISO 14488ISO/DIS 19749ISO/TS 21362ISO 9276-3ISO 9276-5CEN ISO/TS 80004-122412 ISO指南35ISO 27891ISO 17294- 1 ISO指南31EN ISO 11885EN ISO 17034购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS PD CEN/TS 17273:2018 sets requirements for sampling and treatment of the complex matrices in order to obtain a liquid dispersion with sufficiently high concentration of the nano-objects of interest.This document provides guidelines for detection and identification of specific nano-objects in complex matrices, such as liquid environmental compartments, waste water and consumer products (e.g. food, cosmetics). This document requires for the identification a priori knowledge of the nature of the nanoobjects like their chemical composition. The selected detection and identification methods are based on a combination of size classification and chemical composition analysis. Identification can also be supported, e.g. by additional morphology characterization. Currently only Field Flow Fractionation, Electron Microscopy and single particle Inductively Coupled Plasma - Mass Spectrometry fulfil this combination condition.Cross References:ISO 13322-1ISO 9276-2ISO/DIS 21363ISO 9276-6ISO 9276-4ISO 14488ISO/DIS 19749ISO/TS 21362ISO 9276-3ISO 9276-5CEN ISO/TS 80004-1 (ISO/TS 80004-1:2015)EN ISO/IEC 17025:2017CEN/TS 17010:2016ISO/TS 80004-2:2015ISO/IEC 17025:2017CEN ISO/TS 80004-2:2017ISO/TS 80004-1:2015ISO Guide 30:2015ISO/IEC Guide 99:2007ISO 15900:2009ISO 19430ISO 5725-2EN ISO 17294-1ISO/TS 19590ISO 11885ISO 22412ISO Guide 35ISO 27891ISO 17294-1ISO Guide 31EN ISO 11885EN ISO 17034All current amendments available at time of purchase are included with the purchase of this document.
