Review of analytical methods for the measurement of nanoparticle size distribution

JRC scientists evaluated the availability of appropriate analytical methods urgently needed for the detection, quantification and characterisation of nanomaterials in consumer products. Such methods are not only important in the safety testing of nanomaterials but also for implementation of labelling requirements.

The authors conclude that current instrumental techniques providing size distributions have advantages and drawbacks, with the result that there is no single technique at present that can by itself provide a robust analytical method for the purpose of implementing upcoming legislation referring to the definition of nanomaterials.

As the Commission's in-house science service, the Joint Research Centre's mission is to provide EU policies with independent, evidence-based scientific and technical support throughout the whole policy cycle. Working in close cooperation with policy Directorates-General, the JRC addresses key societal challenges while stimulating innovation through developing new methods, tools and standards, and sharing its know-how with the Member States, the scientific community and international partners. Key policy areas include: environment and climate change; energy and transport; agriculture and food security; health and consumer protection; information society and digital agenda; safety and security, including nuclear; all supported through a cross-cutting and multidisciplinary approach.
