The invention relates to analytical instrument engineering, in particular to spectroscopy. The inventive method for measuring spectroscopic properties of bulk products consists in portionwisely supplying a sample in a measurement area. In order to fully fill said measurement area, several portions (at least two) are loaded and alternately placed substantially in different fields of the horizontal section of the measurement area in such a way that the uniformed distribution and the permanent density of the product in the area of measurement are provided. Afterwards, the spectroscopic properties of the sample are recorded in a standstill and the sample is removed from the area of measurement. The inventive device for measuring spectroscopic properties of bulk products comprises a feeding hopper, an input (receiving) opening, a batch loading unit which is provided with means for successively and uniformly distributing the product alternately in the different fields of the horizontal section of the area of measurement, a measuring unit, a unit for closing the area of measurement, an output (unloading) opening and a discharge hopper. Said invention makes it possible to ensure the high uniformity and permanent density of the product in the area of measurement during the measurement of the spectroscopic characteristics of the bulk products.

The invention relates to analytical instrument engineering and can be used for designing calibrating patterns of measuring devices for determining one or several secondary properties of an unknown sample on the basis of the measuring results of a plurality of the primary properties thereof. The inventive method consists in selecting a calibrating set for samples whose secondary properties are known and are defined by means of reference methods, in measuring the primary properties of each said sample by means of a reference device, in converting the measuring results into a form corresponding to the calibratable device, in forming a calibrating pattern enabling to define the analysed secondary properties of the unknown sample on the basis of the measurement of the plurality of primary properties thereof measured by means of the calibratable device. Said method is characterised in that the mathematics for the calibration translations are determined by selecting the combination of samples therefor and the primary properties of each sample are measured by the reference and calibratable devices. The selection of an independent multidimensional calibrating pattern is carried out by comparing the results and by using a method for verifying the accuracy thereof, thereby taking into account the non-linear differences of technical parameters of the calibratable and reference devices and the operating conditions.
