A novel extension to the Nanoparticle Tracking and Analysis (NTA) technique is described. Previously a nanoparticle dispersion’s size distribution could be measured by simultaneously tracking many particles and directly (unlike DLS/SLS) calculating the particle size based on the Brownian motion. This has been extended by looking at the intensity of light scattered by particles. This extra parameter give extra insight into the sample composition of heterogenous mixes of particle materials.
