The disclosure relates to a method for identifying adsorbates deposited on resonance plates. The method includes (i) calculating a candidate mass and candidate position of the adsorbate, disregarding the effect of stiffness, from the measurement of the frequencies of the plate and prior knowledge of the mass of the plate; (ii) using the calculated values as a starting point for calculating the final values of the mass and position of the adsorbate and the different stiffness coefficients from the measurement of the frequencies of the plate; (iii) comparing the values of the candidate mass of the adsorbate and of the calculated coefficients with a set of previously stored reference values corresponding to a catalogue of known adsorbates; and (iv) identifying the adsorbate deposited on the plate as the adsorbate belonging to the catalogue that is most similar to the obtained values.

Method and system for identifying particles, based on multifrequency measurements of resonating plates

An analysis system includes a reflective substrate; a hollow elongate structure with two ends; two polymer supports coupled to the ends and joined to the substrate; a piezoelectric device coupled to the substrate and designed to produce vibrations in the elongate structure; a laser for emitting a beam; a beam splitter; a photodetector; an amplification module; and a processor. The laser beam passes through the cavity and is absorbed by the photodetector, which generates a signal that is transmitted to the amplification module. The amplification module separates the signal into a modulated component and an unmodulated component. The signal is transmitted to the processor to obtain the resonance frequency and reflectance and to provide the piezoelectric device with an excitation signal at the resonance frequency.
