ABSTRACT:
Apparatuses, methods, and systems for measuring mean particle size and concentration of a polydispersion of agglomerates are disclosed. In one embodiment, the apparatuses include a light source; a focusing lens to form a probe volume; a first light detector positioned at a first angular position from the beam of light; and a second light detector positioned at a second angular position from the first direction of the beam of light, the mean particle size and concentration being determined using nearly invariant functions of a ratio of the light scattered measured by the first and second detectors.
