Abstract
A device and process for examining the size of particles suspended in a liquid, in particular for determining the MCV of red blood cells, having a measurement aperture traversed by the suspension and two electrodes arranged in the region of the measurement aperture and connected to evaluation circuitry, each of which electrodes producing one pulse per particle passing therethrough, the amplitude of which pulse is a measure of the volume of the particle. A differential discriminator for the pulse amplitudes and a further discriminator are connected in front of the evaluation circuitry wherein the further discriminator permits the passage of only pulses whose duration is less than the duration of a pulse coming from a single particle which has a maximum amplitude determined by the differential discriminator.
