  • the device includes four electrodes located in the same area. Indicated distinctive features are significant.
  • a four-way electric supply ensures that you can prepare for analysis in the camera. Electrical processes result in the oxidation of organic compounds as a result of electrical reactions. At the same time, on the auxiliary electric power, the excess of the oxidizing agent is restored. These reactions are most complete if the elec- trons are conveniently equipped and have a generous maximum capacity for this type of unit. Complete reactions and reduce the amount of detection required to mix the process in the analysis process.
  • the electrochemical sensor works as follows. When it is turned on 6, it is washed off with bidistilled water, connects to a magnetic stirrer, then it is filled with a working mode. In case of analysis of natural water, when the hard mode is not required to be processed, it can be found in the camera in its dry form, that is why we need to analyze it.
  • the user can be used as it is, because it is easy to use and is cheap to use.
  • Placing electric devices in one area is easier to use than the sensor, since it is used to apply the film.

Abstract

L'invention concerne le mesurage électrochimique et notamment l'analyse électrochimique de la composition d'une solution. Selon l'invention, un capteur électrochimique est constitué d'une chambre en forme de coupe; au fond de la coupe, quatre électrodes sont placées sur un plan, à savoir une électrode principale de mesure, une électrode de comparaison, une électrode d'appoint et une électrode de préparation d'échantillons. L'utilisation d'une électrode de préparation d'échantillons et le recours à l'agitation permettent d'abaisser le seuil de détection et d'augmenter la reproductibilité des résultats.
