摘要： Um ein Verfahren zur Reinigung, Konditionierung, Kalibration, Justage und Konditionierung eines amperometrischen Sensors einer Messeinrichtung zur Bestimmung eines Inhaltsstoffes in einem Elektrolyten mit einer durch eine selektiv durchlässige Membran verschlossenen, den Elektrolyten enthaltenden Messkammer, in der die Arbeitselektrode und eine mit der Arbeitselektrode elektrisch verbundene Referenzelektrode angeordnet ist, wobei die Membran für den zu bestimmenden Inhaltsstoff durchlässig ist, wobei die Bestimmung des Inhaltsstoffes während eines Messintervalls dadurch erfolgt, das eine Spannung zwischen Arbeitselektrode und Referenzelektrode angelegt wird, der Strom, der über die elektrische Verbindung von Arbeitselektrode und Referenzelektrode fließt, gemessen wird und aus dem gemessenen Strom auf den Inhaltsstoff rückgeschlossen wird, bereitzustellen, das eine vergleichbare oder sogar eine bessere Reinigungs- und Konditionierwirkung als die aus dem Stand der Technik bekannten Verfahren aufweist, für das jedoch ein einfacherer apparativer Aufbau ausreichend ist, wird ein Verfahren beschrieben, das dadurch gekennzeichnet ist, dass ein Konditioniermittel in der Messeinrichtung erzeugt wird, wobei als Konditioniermittel entweder ein Oxidationsmittel, welches an der Arbeitselektrode reduziert wird, oder ein Reduktionsmittel, welches an der Arbeitselektrode oxidiert wird, verwendet wird.

摘要： The invention relates to an electrochemical method and to a device for determining the content of DOC and/or TOC and/or IC in an aqueous sample by means of anodic oxidation of electrodes in a closed electrolytic cell, wherein the carbon is at least partially oxidized into carbon dioxide (CO
2 ). The formed carbon dioxide is collected in a closed gas chamber, wherein in the range of the substantially linear rise of the CO
2 content in the gas chamber, the speed at which said rise occurs is determined, and said speed is used in an evaluating unit to determine the content of DOC and/or TOC and/or IC.

摘要： In the invention, a back titration and titer determination can be made using a back coulometric titration. When the iodine exists in a solution put in the titration flask with electrolytic electrodes, a back coulometric titration is performed to produce iodine ions from the iodine at the anode of the electrolytic electrodes. Where the solution is a dehydrated solvent including a Karl Fischer reagent for a volumetric titration, the titer can be determined by the back coulometric titration. Where the solution is anolyte in which the iodine remains after the coulometric titration in the coulometric titration method, the water content in the sample is found from the quantity of electricity consumed by the coulometric titration and the quantity of electricity consumed by the back coulometric titration. Where the solution is anolyte in which the iodine remains by adding Karl Fischer reagent in the volumetric titration method, the water in the sample put in the titration flask is found from the added amount of Karl Fischer reagent and the quantity of electricity consumed by the back coulometric titration.

摘要： A method of determining one gas in the presence of another, where the one gas is reactive with an electrochemical product of the other, comprises
applying the gases to one side of a membrane permeable to the two gases, the other side of the membrane retaining a solvent for both gases and forthe electrochemical product,
applying, for a predetermined duration through a working electrode in contact with the solvent, a potential which electrolyses (e.g. reduces) the (dissolved) other gas to form the said electrochemical product,
applying, through the working electrode, a potential for reconverting the product to the dissolved gas,
measuring, at a predetermined instant or integrated over a predetermined time slot, the current flowing at the reconversion potential, and,
from the amount by which the measured current (or integrated current, i.e. charge) falls short of the current when the said one gas is absent, determining the concentration of the said one gas.
Optionally, the said other gas is also determined, by measuring the current flowing at the first potential.
The one gas may be carbon dioxide. The other gas may be oxygen. The solvent may be dimethylsulphoxide.
