NANOTECHNOLOGIES - SAMPLE PREPARATION FOR THE CHARACTERIZATION OF METAL AND METAL-OXIDE NANO-OBJECTS IN WATER SAMPLES

Established by adopting ISO/TR 20489:2018(E) Nanotechnologies — Sample preparation for the characterization of metal and metal-oxide nano-objects in water samples by reprinting at an identical level, using the English version of ISO as the basis. - Provides an overview of sample preparation guidelines (e.g., preparation and size separation) for analytical methods used with surface and drinking water. May include the quantity and types of metal and metal-oxide nanoobjects involved, as well as collection from sources and sample storage, pre-concentration of the analyzed substance, and separation.
