Nanoparticle Tracking Analysis (NTA) utilizes the properties of both light scattering and Brownian motion in order to obtain the particle size distribution and concentration of nanoparticles in liquid suspension. The scattered light from individual particles is tracked providing the diffusion coefficient of each particle measured. This provides high resolution particle size distributions and concentration values independent of particle material.
