Patent ID: 8030948

Claim:
A device for analyzing the composition of the contents of a container comprising: electromagnetic field emitting/receiving means at least several frequencies comprising a determined range of frequencies, means for supporting the container, the contents of which have to be analyzed, suitable for ensuring accurate relative positioning between the emitting/receiving means and the container, means for measuring the complex impedance of the emitting/receiving means influenced by the load formed by the container and its contents, representative of the complex dielectric characteristics of the container and its contents, means for obtaining at least one additional physical datum relating to a characteristic of the container, the additional physical datum comprising the mass of the container and its contents, and means for providing information relating to the nature of the contents of said container depending on the measured complex impedance and on the mass of the container and its contents, the mass of the container and its contents being used for correcting the amplitude of the measured complex impedance.
