  • Method for characterizing a liquid sample containing particles
    Patent number: 9921147
    Abstract: The invention is a method for characterizing a liquid sample, said liquid sample containing particles, the method comprising the following steps: a) illuminating said sample using a light source that is able to emit an incident light wave towards the sample; b) detecting, using a photodetector, a light wave transmitted by the sample thus illuminated; c) characterizing the sample depending on an intensity of the light wave detected by the photodetector. The method comprises, prior to step c), applying an acoustic wave to the sample, said acoustic wave forming pressure nodes and pressure antinodes in the sample, so as to separate, in the latter, a poor portion, poor in particles, and rich portion, rich in particles, such that, in step c), the sample is characterized: either on the basis of the intensity of the light wave transmitted by the poor portion; or on the basis of the intensity of the light wave transmitted by the rich portion.
