Abstract
A system for detecting particles in a gas stream comprises a Faraday collector separating charged particles into positive and negative streams to be detected. The Faraday collector includes a plurality of interdigitated wires, with a first plurality of wires charged with a positive potential and a second plurality of wires charged with a negative potential to separate particles in the gas stream into the positive and negative streams.
