Abstract

The invention relates to a device for analysing the composition of the contents of a container comprising:

• transmitter/receiver means (40) of an electromagnetic field having at least several frequencies in a determined frequency range,
• support means (5) of a container (R) whereof the contents have to be analysed, adapted to ensure precise relative positioning between the transmitter/receiver means (40) and the container (R),
• means (50) for measuring the complex impedance of the transmitter/receiver means influenced by the load constituted by the container (R) and its contents, representative of the complex dielectric characteristics of the container and its contents,
  characterised in that it further comprises spectral analysis means of the contents of the container for measuring the absorption of waves by the container and its contents, and means (50) for providing information relative to the nature of the contents of said container (R) as a function of the complex measured impedance and of the absorption measuring.

Claims

1. A device for analysing the composition of the contents of a container comprising:

transmitter/receiver means of an electromagnetic field with at least several frequencies comprised in a determined frequency range,

support means of a container, the contents of which have to be analysed, suitable for ensuring accurate relative positioning between the transmitter/receiver means and the container,

means for measuring the complex impedance of the transmitter/receiver means influenced by the load constituted by the container and its contents, representative of the complex dielectric characteristics of the container and its contents,

wherein the device further comprises spectral analysis means of the contents of the container for measuring the wave absorptions by the container and its contents, and means for providing information relative to the nature of the contents of said container as a function of the complex measured impedance and of the absorption measuring.

2. The device as claimed in claim 1, wherein the support means comprise a cavity formed by a channel the generatrices of which are tilted downwards away from an open front face through which a container is introduced, the spectral analysis means comprising at least one receiver placed under the cavity.

3. The device as claimed in claim 1, wherein the spectral analysis means are suitable for sending waves, the wavelengths of the waves being in the infrared spectrum, and for measuring the absorption of said waves by the container and its contents.

4. The device as claimed in claim 1, wherein the spectral analysis means are suitable for sending waves, the wavelengths of the waves being comprised between 0.7 μ

m and 3 μ

m.

5. The device as claimed in claim 4, wherein the spectral analysis means are suitable for sending waves, the wavelengths of the waves being comprised between 1000 nm and 1400 nm.

6. The device as claimed in claim 1, wherein the spectral analysis means comprise at least one transmitter suitable for sending waves and a receiver placed so as to receive the waves emitted by the transmitter.

7. The device as claimed in claim 6, wherein the transmitter and the receiver are placed in the sagittal plane of the support means to the right of one another, such that the waves emitted by the transmitter pass through the container to be analysed prior to being received by the receiver.

8. The device as claimed in claim 7, wherein the transmitter is placed on the support means and the receiver is placed under the support means.

9. The device as claimed in claim 6, wherein the transmitter and the receiver are placed in the median plane of the support means opposite one another, such that the waves emitted by the transmitter pass through the container to be analysed prior to being received by the receiver.

10. The device as claimed in claim 1, wherein the spectral analysis means comprise a plurality of transmitters placed along the support means and a plurality of associated receivers placed so as to receive the waves emitted by the plurality of transmitter.

11. The device as claimed in any one of claims 4 to 9, wherein the transmitters are placed in the sagittal plane of the support means, said transmitters being alternatively placed on and under the support means, and being associated with receivers placed to the right of said transmitters.
