ABSTRACT:
The invention sorts small particles by subjecting them to a charging and motivating field produced by a single positively charged electrode. The magnitude of the charge placed on the particle passing the electrode is a function of the observed particle parameters. Once the particle has been deflected in accordance with its observed parameter, the particle may be collected for further study.
