The invention relates to a method for determining the rate at which a mixture in suspension sediments or forms a skim involving applying a test specimen of the mixture in suspension to a photon micro-resonator, application of a first optical system to the input of the photon micro-resonator bearing the test specimen of the mixture in suspension, acquisition and recording of a second optical signal, delivered on the output of the micro-resonator bearing the test specimen of the mixture in suspension, and determining an item of information indicative of a rate at which the mixture sediments or forms a skim from the recorded second signal using successive iterations of spectral analysis of the second optical signal.
