It has been demonstrated the feasibility of an ambient air on-line characterisation of manufactured nanoparticles combining physical characterisation using dedicated DMA technique and chemical identification with field optimised laser-induced breakdown spectroscopy (LIBS) technique. Results obtained on demonstrator-based instrument should show detection limit around ng/m(3) in UV-IR nanosecond pulse regime.
