What is PD CEN/TS 17273 - Nano-objects in complex matrices about?
PD CEN/TS 17273 discusses nano-objects in complex matrices in nanotechnologies. PD CEN/TS 17273 outlines requirements for sampling and treatment of the complex matrices to obtain a liquid dispersion with a sufficiently high concentration of the nano-objects of interest. PD CEN/TS 17273 provides guidelines for the detection and identification of specific nano-objects in complex matrices, such as liquid environmental compartments, wastewater, and consumer products (e.g., food, cosmetics). PD CEN/TS 17273 requires the identification of 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 fulfill this combination condition.
