Abstract
Disclosed is a flow through particle analyzing cell differentiating apparatus for optical and electronic measurements on a stream of particles in which a hydrodynamically focoussed stream is passed into and through a point focussed beam of radiated energy whereby the beam is scattered by the stream to impinge upon light responsive signal operating members disposed adjacent the cell at angular positions relative to the beam axis of from about 10.degree. to 70.degree..
