VOLT-AMPERE ANALYZER, ELECTROCHEMICAL TRANSDUCER OF VOLT- AMPERE ANALYZER (ITS VARIANTS) AND AID MIXING SOLUTION OF VOLT-AMPERE ANALYZER Russian patent published in 1999 - IPC

FIELD: volt-ampere analysis of food, agricultural products and any other objects of environment for content of toxic and other tested impurities. SUBSTANCE: volt-ampere analyzer has former of polarizing voltage connected to electrochemical cell with electrodes whose indicator electrode is mechanically joined to output of aid mixing solution of electrochemical cell and is electrically connected to input of measurement circuit connected correspondingly to input and output of unit of control and data output, aid mixing solution of electrochemical cell controlled by unit of control and data output. Given volt-ampere analyzer is characterized by insertion of device that deactivates dissolved substances impeding analysis coupled to one electrochemical cell as minimum and forming together with it single unit of electrochemical transducer controlled by signals from unit of control and data output. In agreement with first variant device that deactivates dissolved substances in electrochemical transducer of volt-ampere analyzer provides for neutralization of organic substances and oxygen and is manufactured in the form of tubular source of ultraviolet radiation that has bent circuit ( U-shaped, for example ) inside which at least one electrochemical cell is positioned. In correspondence with second variant device that deactivates dissolved substances ensures neutralization of organic substances and presents solution ozonizer fabricated in the form of ozone generator which outlet is connected to gas regulators which number is equal to number of electrochemical cells which outlets are connected via branching tubes to each electrochemical cell. Aid mixing solution of electrochemical cell includes magnetic coil with core, pulse generator and mobile vibrator mechanically coupled to indicator electrode of electrochemical cell, permanent magnet anchored on mobile vibrator and feedback forming circuit which output is connected to input of pulse generator whose output is linked to input of feedback forming circuit and electromagnetic coil. Technical result of invention consists in deactivation of dissolved substances and oxygen impeding analysis in the course of entire process of analysis which provides for high sensitivity and productivity of volt-ampere analysis. EFFECT: high sensitivity and productivity of volt-ampere analysis. 10 cl, 6 dwg
