“…The measurement of particle number, mass, shape and size in harsh industrial environments is challenging but aspirational because in situ measurements are needed to support process automation. A unique set of instruments with potential for the characterisation of APM during metal smelting processes was assessed 35 for interrogating simulant Al 2 O 3 and chalcopyrite particles aerosolised in a dust chamber. The instrumentation, all contactless and working in real-time, included: stroboscopic imaging for confirming particle sphericity and measuring particle number density; LIBS for estimating particle number density and compositional analysis; and LII for classifying particles based upon their tendency to incandesce.…”

Aerodynamic lenses can increase the local particle number density of the aerosol beam. The particle number density of aerosol has an important effect on the excitation probability and spectral intensity of laser-induced plasma. Therefore, aerodynamic lenses have the potential to improve the identification efficiency of Laser Induced Breakdown Spectroscopy (LIBS) in aerosol real-time monitoring. In this study, the effects of an aerodynamic lens on laser excited aerosol particles were developed by experiments and simulations. The process of aerosol beam passing through an aerodynamic lens was simulated by using the CFD software FLUENT. The simulation results show that the setup can increase the aerosol concentration by three orders of magnitude. The Aerosol Focusing-Laser Induced Breakdown Spectroscopy (Aerosol Focusing-LIBS) experimental setup is established. The experimental and simulation results are in good agreement. And the experimental results show that the laser excitation probability has increased by about 5 times, the average intensity of the excitation spectrum has increased by about 3 times.
