Abstract: A device for spectroscopically analysing a grain sample may include a first infrared analysis module, a second fluorescence analysis module, a third specific weight analysis module and a processing module. Each of the first and second modules may include a measurement chamber, an excitation submodule to emit at least one electromagnetic radiation towards at least a portion of the sample, a measurement submodule, and a draining system. The third analysis module may include a container, and a measurement submodule to measure a specific weight of the sample. A processing module may be connected to each of the modules and may include a memory to receive data transmitted by a communication network, the data including electromagnetic spectra acquired and specific weights measured, and a processor to couple the data received in the memory and to determine an indicator of quality of the sample from the coupled data.

Abstract: A device is for analyzing a heterogeneous sample (S). The device includes a measurement module having a reservoir configured to accommodate the sample (S), a first infrared spectroscopy subassembly and a second fluorescence spectroscopy subassembly. The first subassembly includes a diffusing optical element which is positioned so as to allow the implementation of reliable infrared spectroscopy measurements with a high precision without degrading the fluorescence spectroscopy measurements which take place on the same sample. The device includes a processing module connected to the measurement module by a communication network and a processor configured to analyze the data obtained by infrared spectroscopy and fluorescence spectroscopy.
