DESCRIPTION
PD ISO/TR 20489:2018
This standard PD ISO/TR 20489:2018 Nanotechnologies. Sample preparation for the characterization of metal and metal-oxide nano-objects in water samples is classified in these ICS categories:
- 07.120 Nanotechnologies
This document provides an overview of approaches of sample preparation (i.e. pre-treatment and size-fractionation) for analytical measurements applied to surface and drinking water, potentially containing relevant amounts and types of metal and metal oxide nano-objects, including collection from source and storage of samples, pre-concentration of analytes, and their fractionation.
