    Abstract - (Show below) - (Hide below)

    Gives guidance to measure size distributions of particles in any two-phase system, such as powders, sprays, aerosols, suspensions, emulsions and gas bubbles in liquids, through analysing their angular light scattering patterns. Does not cover the specified requirements of particle size measurement of specific products. Applies to particle sizes between 0.1 um and 3 mm.
