Abstract

A device for analyzing the composition of the contents of a container. The device includes a transmitter/receiver with an electromagnetic field having at least several frequencies in a determined frequency range, a container support for a container (R) whose contents are to be analyzed. The support is adapted to ensure precise relative positioning between the transmitter/receiver and the container (R). A measuring unit measures the complex impedance of the transmitter/receiver influenced by the load constituted by the container (R) and its contents. A spectral analyzer analyzes the contents of the container for measuring the absorption of waves by the container and its contents. An information providing unit provides information relative to the nature of the contents of the container (R) as a function of the complex measured impedance and of the absorption measuring.
