Abstract

A particle study apparatus, in response to passage of particles in suspension through a sensing device, produces electrical pulses which are proportional in amplitude to the size of the respective particles. The appratus includes a system for ascertaining the particle size above and below which size predetermined fractions of one of the total mass and total number of the particles in suspension are respectively included. If total mass is desired electrical quantities are accumulated in response to each electrical pulse which are proportional to the amplitudes of the electrical pulses. If total number is constant electrical quantities are accumulated in response to each electrical pulse.
