Abstract
The invention relates to an electro-optical device for measurements of flow for the characterization of microparticles, comprising a measurement chamber (CUM) in which there circulates the flow of the fluid to be characterized, at least two luminous sources (S1,S2) of disjoint spectra, a device for measuring resistivity (RES), and at least three other detectors (D1,D2,D3) each allowing the measurement of an optical parameter, the optical parameters being chosen from among fluorescence (FL), extinction (EXT), wide angle diffraction (SSC) and small angle diffraction (FSC).
