| Resumen: | This Technical Specification provides guidelines for detection and identification of nano-objects in complex matrices, such as liquid environmental compartments, waste water and consumer products (e. g. food, cosmetics). This Technical Specification assumes a priori knowledge of the nature of the nano-objects like their chemical composition. The selected detection and identification methods are based on combination of size classification and chemical composition analysis. Identification can also be supported e. g. by additional morphology characterization.The requirements for sampling and treatment of the complex matrixes in order to obtain a liquid dispersion with sufficiently high concentration of the nano-objects of interest are given. Examples for sample preparation are provided.The document provides links to measurement method standards if available. This Technical Specification covers appropriate methods: Field Flow Fractionation, Electron Microscopy and single particle Inductively Coupled Plasma - Mass Spectrometry. |
