1. An electrostatic particle sorting system comprising:

  • (a) flow means for establishing the flow of a continuous particle containing stream;

    (b) perturbation means for perturbing said stream with at least a preselected frequency and amplitude to cause said stream to form a breakpoint at which said stream becomes a series of discrete droplets;

    (c) stream surface sensing means for sensing at least the light scatter characteristic of said stream at a stream sensing point disposed above said breakpoint and at a preselected distance from said perturbation means; and

    for producing a surface character output signal which is proportional thereto;

    (d) marker signal means for selectively varying the perturbation caused by said perturbation means to create a marker signal in said stream; and

    (e) marker signal detection means for monitoring said surface character output signal to detect the arrival of said marker signal at said stream sensing point.
