Dynamic light scattering, ultrasound spectroscopy and electrical resistance tomography were investigated for online monitoring of nanoparticle suspensions. This integrated system provides real time information about particle size distribution, zeta potential and particle concentration and visualises the mixing quality between particles and liquids. As particle size distribution is an indicator of the quality of particulate products, zeta potential measures the stability of colloidal particles and tomography shows particle concentration and the mixing quality between particles and liquids, this integrated multiple sensor system can be applied to nanoparticle manufacturing processes for online process and product quality control.
