Abstract
A particle analyzing apparatus comprising a reflector chamber containing an electrolyte and having a concave reflector surface with a first focus and a second focus; entraining structure, having an introduction tube for providing and moving a stream of particles suspended in an electrolyte solution through the first focus; a source of radiant energy for illuminating the particles as they pass through the first focus to produce a source of detectable radiation signals, which reflect off the concave reflector surface to be subsequently collected and analyzed; an exit tube coaxially aligned with the introduction tube; a sensing orifice mounted in the tip of the introduction tube or the exit tube; and a pair of energized electrodes disposed in the electrolyte solution on either side of the orifice, whereby the orifice creates a constricted electrical path in which the stream of particles generate electrical impedance signals as they move therethrough.
