WebWhen the laser beam strikes the stream, the majority of the photons will pass through unobstructed. Some of these photons will diverge slightly, primarily via light diffraction, from their path as they contact the membranes of passing cells.A detector is placed in line with the laser path (on the opposite side of the stream) and this “scattered” light is collected. WebA particle size distribution indicates the percentage of particles of a certain size (or in a certain size interval). These intervals are also called size classes or fractions.
