ISO 22412:2017 specifies the application of dynamic light scattering (DLS) to the measurement of average hydrodynamic particle size and the measurement of the size distribution of mainly submicrometre-sized particles, emulsions or fine bubbles dispersed in liquids. DLS is also referred to as 'quasi-elastic light scattering (QELS)' and 'photon correlation spectroscopy (PCS),' although PCS actually is one of the measurement techniques.
