FIELD: physico-chemical analysis and examination of aqueous samples. SUBSTANCE: process of analysis of composition of liquid solutions of electrolytes placed in cell of dielectric material consists in measurement of electrical characteristics of electrodes lowered into electrolyte solution. Similar electrodes are used to lower into cell. Permanent magnetic field with lines of force parallel to shortest straight line between electrodes is created in cell. After switching on permanent magnetic field kinetic dependence "potential-time" is obtained on which basis quantitative composition of solution is determined. EFFECT: decreased time and improved authenticity. 2 dwg, 1 tbl
