Nanoparticle Characterization Systems

Nanoparticle characterization is a process used to characterize and control nanoparticles for material synthesis and other applications.

Because these particles are too small to investigate using visible light, nanoparticle characterization systems use electrophoretic light scattering (ELS), dynamic light scattering (DLS), and static light scattering (SLS) to discover particle size, occurrence of aggregates in a sample, particle count, molecular mass and zeta potential, an essential indication of the integrity of colloidal dispersions. Most conventional systems can identify particle sizes ranging from 0.3 nanometers to 10 micrometers.

Some nanoparticle characterization systems have analysis software that can track and identify particle size concurrently, and then combine scatter intensity information with size distributions to image data in three dimensions. Some systems capture video of each sample for further evaluation.
