Abstract: 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.
