METHOD OF MEASURING SPECTROSCOPIC PROPERTIES OF BULK PRODUCTS AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2025 - IPC G01N21/25 

FIELD: physics.

SUBSTANCE: invention relates to analytical instrumentation and relates to a method for measuring spectroscopic properties of an analysed sample in form of a single sample of a loose solid product. Method includes delivering the analysed sample to the measurement zone, fixing the analysed sample on the diaphragm dividing the measurement chamber in the measurement zone due to the pressure difference, recording the spectroscopic properties of the analysed sample, performing at least one repeated measurement by changing the position of the analysed sample in the measurement zone by mechanical tilting and rolling the analysed sample in the measuring chamber, sorting the analysed sample in the sorting unit depending on the results of spectroscopic measurements, unloading the analysed sample from the measurement zone. Measuring chamber, the device for tilting and rolling the analysed sample, the unit for unloading the analysed sample from the measuring chamber and the sorting unit are one indivisible unit.

EFFECT: high quality of the obtained spectra and high reliability of measurements.
