METHOD AND DEVICE FOR CALORIFIC CAPACITY EVALUATION Russian patent published in 2017 - IPC G01N33/22 G01N33/46 G01N23/87 

FIELD: measuring equipment.

SUBSTANCE: method for evaluating calorific capacity of a biomaterial comprises the following stages: correlating the amount of radiation transmitted through several different reference materials. The mentioned radiation is X-ray radiation of at least two energy levels with calorific capacities of the mentioned reference materials, obtained by calorimetric measurements, irradiating the biomaterial with X-ray radiation of the mentioned at least two different energy levels, and measuring the amount of radiation transmitted through the mentioned biomaterial at the mentioned energy levels. The method additionally comprises the stage of determining the amount of transmission through the biomaterial for each energy level based on radiation passing through the mentioned biomaterial, and on the basis of the mentioned specified transmission values and the mentioned correlation, the estimated calorific capacity of the mentioned biomaterial is determined. A device for determining the calorific capacity of a biomaterial is also disclosed.

EFFECT: improved accuracy of evaluation.
