Abstract :

The development of nanotechnologies inevitably induces the need for analytical methods capable of characterizing nanomaterials such as nanoparticles and nanotubes. The challenge remains important due to the diversity in size, shape, chemical composition of natural and engineered nano-objects combined with the complexity of the surrounding media. Some years ago, Field-Flow Fractionation (FFF) coupled with UV, Multi-Angle Light Scattering (MALS) and atomic mass spectrometry (ICPMS) has been proposed as a powerful analytical strategy for such challenge. In this presentation FFF will be presented from its principle to its analytical performances. Different examples of applications in material sciences and environmental media will be presented in order to illustrate the capabilities of FFF-multidetection.
