Abstract

In an. apparatus for sorting particles suspended in a liquid, a jet of the liquid is broken into a regular train of droplets by accoustic pulses and a sensor 29 measures a selected characteristic of each particle that passes it and causes an electrostatic charging collar 37 to charge each droplet in accordance with the measured characteristic of any particle it may contain. Electrostatic deflecting plates 39, 41 then direct each droplet into an appropriate collecting vessel or onto an appropriate portion of a moving strip of blotting paper. The selected characteristic may be size, radioactivity, fluorescence, luminescence, electrical conductivity, or light transmissibility. or reflectivity. The particle concentration should be such that about one in seven droplets will contain a particle and the collar 37 should charge one or more droplets ahead of and behind the droplet expected to contain the particle.
