ABSTRACT:
Disclosed is a particle analyzing apparatus having a flow cell with an elongated or tube-like aperture for receiving a liquid suspension of particles and for providing a smooth fluid flow therethrough and electric field and current, generated in and essentially limited to a relatively small portion of the aperture, for producing electrical signals when the particles pass therethrough.
