APPARATUS FOR THE DETECTION OF PARTICLES

摘要

This invention provides an apparatus for the detection of individual particles in a suspension flowing through a transparent flow cell, further comprising of means to irradiate the suspension in this flow cell and means to detect the light emitted by the suspended particles. The irradiation means provides two identical coparallel and overlapping laser beams, with a lateral, relative displacement more or less equal to the beam radius, and polarized in relative orthogonal directions. This apparatus is also suited for the detection of larger particles.
