Abstract: The invention relates to the use of a physical-technological radiation source in a method for cleaning and conditioning a sensor of a measuring device for determining a constituent substance in a sample, a sensor and an electrochemical measuring device for carrying out said method.

Abstract: A method for cleaning, conditioning, calibration, adjustment and conditioning of an amperometric sensor of a measuring device includes generating a conditioning agent in the measuring device, wherein either an oxidising agent which is reduced at the working electrode or a reducing agent which is oxidised at the working electrode is used as conditioning agent.

Abstract: In order to provide a method for cleaning, conditioning, calibration, adjustment and conditioning of an amperometric sensor of a measuring device for determining a content substance in an electrolyte, with a measuring chamber, sealed by a selectively permeable membrane, containing the electrolyte, in which the working electrode and a reference electrode connected electrically with the working electrode are arranged, wherein the membrane is permeable to the content substance which is to be determined, wherein the determination of the content substance takes place during a measuring interval in that a voltage is applied between the working electrode and reference electrode, the current which flows via the electrical connection between working electrode and reference electrode is measured and the content substance deduced from the measured current, said method achieving a comparable or even a better cleaning and conditioning effect than the methods known from the prior art, but for which a simpler equipment set-
