Abstract

An apparatus for identifying specific particles of various microstructures within a fluid, characterized by conduit means containing a sample of said fluid with said particles therein, scanning means that effectively scan the microstructure of individual particles in said fluid as a consequence passing said fluid through a defined region, detecting means that respond to said scanning means to develop an electrical output signal, and means to analyze and treat said output signal to obtain from it a plurality of output signals that each it corresponds to a specific constituent in particles of said sample.
