A system for the differentiation of plastic and non-plastic particles in suspension in a liquid, and the method of use thereof. The system having a channel for constraining and presenting the liquid to a detector, the detector having at least one transmit electrode for emitting electrical current to at least one receive electrode. Circuitry provides the current input and received electrical signals measurement capacities. Particles passing the receive electrodes alter the received electrical current according to the particle's dielectric properties, the circuitry records the received signals and discerns a particle's nature, most often plastic from non-plastic, from the differential signal of these received signals as a function of frequency.
