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.
摘要翻译：在本发明中，可以使用反向电量滴定法进行反滴定和滴定度测定。当放置在具有电解电极的滴定瓶中的溶液中存在碘时，进行背电量滴定以从电解电极的阳极处的碘产生碘离子。当溶液是包含用于体积滴定的卡尔费休试剂的脱水溶剂时，滴定度可以通过后面的库仑滴定测定。如果溶液是在库仑滴定法中在库仑滴定之后碘保留的阳极电解液，则样品中的水含量是从库仑滴定消耗的电量和由后面的库仑滴定消耗的电量中找到的。当溶液是通过在体积滴定法中加入卡尔费休试剂而残留碘的阳极液时，从卡尔费休试剂的加入量和背部消耗的电量中可以发现放入滴定瓶中的样品中的水库仑滴定。

摘要： An apparatus comprises a transducer having a first output signal and arranged to receive an electrical input. The transducer switches the first output signal between an ON and OFF state. The apparatus comprises a chemical sensing surface coupled to the transducer arranged to receive a chemical input.A signal generator oscillates one or more of said inputs to vary the switching point of the transducer. The oscillating input may be the chemical input and/or the electrical input. The output signal may be a pulse whose period ON or OFF is determined by the oscillating input modulated by the chemical input.

摘要： Beschrieben wird ein neues coulometrisches Verfahren zur kontinuierlichen Bestimmung oder Detektion von Gaskomponenten in einem Gasgemisch, die reaktionsfähig sind, wie Schwefeldioxid, Ammoniak, Schwefelwasserstoff, Stickoxide, Kohlendioxid.
Das Verfahren zeichnet sich dadurch aus, daß die zu bestimmende Gaskomponente A (Analyt) eines Gasgemisches in einem geeigneten Elektrolyten chemisch mit einer vorher elektrolytisch mit Hilfe von zwei Generatorelektroden (7,11) im Überschuß erzeugten spezifisch reaktionsfähigen Substanz in einer durch eine Diffusionsbarriere (10) vom Gasgemisch getrennten Reaktionskammer (16) als Teil der Elektrolytkammer (13) umgesetzt wird. Dabei wird dieses Abfangreagenz verbraucht, was mit einem geeigneten Indikatorsystem registriert wird.
Je höher die Konzentration der Gaskomponente A im Gasgemisch ist, desto höher ist nach den Fick'schen Gesetzen die in die Elektrolytkammer (13) eindiffundierende Gasmenge und umso größer ist der Verbrauch des Abfangreagenz und damit der Gradient des Indikatorsignals.
Davon ausgehend wird die Änderungsgeschwindigkeit (Indikatorsignal-Änderung pro Zeit, also: mV/s, mA/s, oder umgewandelt in Konzentrationsänderung pro Zeiteinheit) gemessen oder über eine Kalibrierung mit der jeweils aktuell vorliegenden Konzentration in Verbindung gebracht. Durch diese relativ kurzzeitigen Gradienten-Messungen werden langfristige Drifterscheinungen der Indikations-Messung kompensiert.

摘要： PCT No. PCT/GB93/00680 Sec. 371 Date Aug. 26, 1994 Sec. 102(e) Date Aug. 26, 1994 PCT Filed Apr. 1, 1993 PCT Pub. No. WO93/22668 PCT Pub. Date Nov. 11, 1993.An ammonia gas sensor 16 is housed within a container 14 partially immersed in a solution 2 containing ammonium ions. An electrochemical generator 6, 8, 10 generates hydroxyl ions in a region of the solution 2 adjacent the container 14. This converts ammonium ions to ammonia gas which is sensed by the sensor 16 having passed through a gas-permeable member 12. This sensing provides an indication of the concentration of ammonium ions in the solution 2.

摘要： Eine diaphragmalose Messzelle (1) für die coulometrische Karl Fischer Titration weist eine grossflächige Anode (4) und wenigstens eine Kathode (3) mit wesentlich kleinerer Oberfläche auf. An der Kathode entstehen hohe Stromdichten, welche bei entsprechender Zusammensetzung der Lösung (10) die turbulente Erzeugung von Wasserstoff-Blasen ermöglicht. Die Anode (4) der Generator-Elektrode (2) weist dabei eine Schmalseite auf, mit welcher sie der Indikator-Elektrode (7) zugewandt ist.
