Abstract
Particle detection and characterizing apparatus has an insulating tube along which the particles flow. Five electrodes spaced along the outside of the tube are connected via amplifiers to a processor arranged to measure the charge on the particles. The apparatus also includes a laser and photomultiplier tube arranged to measure the size of the particles so that the nature of the particles can be characterized from their electrical charge and size.
