ABSTRACT:
The present invention relates to a device for analyzing the composition of the contents of a receiver comprising: means (40) for emitting/receiving an electromagnetic field at a variable frequency over a determined frequency range, means (22) for supporting a container (R), the contents of which should be analyzed, adapted in order to provide relative accurate positioning between the emitting/receiving means (40) and the container (R), means (50) capable of measuring the complex impedance of the emitting/receiving means influenced by the load formed by the container (R) and its contents, representative of the complex dielectric characteristics of the container and of its contents, and means (50) capable or providing a piece of information related to the measured complex impedance and consequently to the nature of the contents of said container.
