FIELD: chemistry.
SUBSTANCE: methods of determining the quantitative composition of a multi-component medium includes placement of a sample in a cell of a differential scanning calorimeter and supply of liquid with the known volumetric thermal expansion coefficient and known volumetric heat capacity into the cell. The total thermal capacity and the total volumetric thermal expansion coefficient of the sample and liquid, located in the cell, are determined and volumes of sample-constituting components are determined by the solution of a system of equations.
EFFECT: increased accuracy, reliability and rate of determination of volumes of a multi-component medium components.
