ABSTRACT:
A novel method and apparatus for automatically setting the time delay for relatively charging droplets in an electrostatic particle sorting system is disclosed. By utilizing a movable sheath sensing means for sensing the light scatter and extinction of this stream, the flow rate and distance to breakpoint are automatically measured and used to calculate and set the timing delay circuitry. This insures that droplet charging at the breakpoint will occur synchronously to produce selective relative charging of those droplets containing particles to be sorted.
