Particle density (particle count)

Particle density, in the context of particle counts, is a measurement of the number of particles in a spatial unit of a particle-bearing medium. Where the spatial unit is one of volume, the medium is likely to a fluid; in another class of cases, the unit is one of area of a surface, and the particles rest on or adhere to that surface.
