FIELD: chemistry. ^ SUBSTANCE: test sample is put into an aqueous solution/suspension with mineral salts and/or acids and/or alkalis in a defined amount in a sampling vessel (1) using blades (2) of a mixer with an electric drive. Resistance offered by the blades (2) of the mixer by the sample during movement is measured, for which torsional forces acting on the electric motor of the drive are measured with strain gauges from the beginning of the movement process, where the said drive is fitted with possibility of rotation, and measurement ends when maximum torque is achieved, wherein the measurement process is monitored, controlled and analysed by a program. ^ EFFECT: invention enables to obtain more accurate analysis results independent of the sample and heat effects with minimum amount of the sample. ^ 5 cl, 4 dwg |
