In general, the acquisition of scattered light intensities of particles under thermal motion is deployed for nanoparticle characterisation (principle of dynamic light scattering (DLS)). Sympatec NANOPHOX brings Photon Cross-correlation Spectroscopy (PCCS) to life, which allows for high resolution nanoparticle size analysis in high concentrated suspensions and emulsions ranging from 0.5 nm to 10,000 nm with minimum sample preparation.
