PARTICLE DETECTION SYSTEM AND COMPONENTS THEREOF

摘要

A combined impedance and fluorescence particle detection system (10) comprising an optically transmissive plate (30) having an orifice (44) for the flow of particles therethrough, a light source (31) which operably directs light on a particle at the orifice, and a light detector (32) positioned so as to detect light which is emitted by the particle, and wherein the plate acts as a waveguide to direct light along part of its path between the light source and light detector.
