DEVICE FOR DETERMINATION OF COMPONENTS CONCENTRATION OF STRONG ELECTROLYTES MIXTURE Russian patent published in 2017 - IPC G01N27/26 

FIELD: measuring equipment.

SUBSTANCE: device for determining the concentration of components of a mixture of strong electrolytes contains a recuperative heat exchanger, an automatic temperature measurement and control system, a conductometer with a flow measuring cell, a measuring device with a sensor for measuring the temperature of a solution in a measuring cell and a computer. According to the invention, the device further comprises a system for automatically diluting the analytes to be analysed with a solvent. The system of automatic dilution of the analysed mixtures with a solvent is equipped with series-connected measuring vessels of various volumes, electric valves for filling the measuring vessels, overflowing excess liquid and draining the liquid, and also with a solvent tank equipped with an overflow tube, electric valves for filling the solvent tank with liquid and draining the liquid, mixer for mixing dilute mixtures of electrolytes with a solvent with a magnetic stirrer placed in it, equipped with an electric valve for supplying the diluted mixture to a recuperative heat exchanger.

EFFECT: increasing the accuracy of measurements and reducing operating costs.
