摘要： The invention is directed to a dosimeter for detecting gaseous substances or substances dissolved in liquids. The dosimeter includes a detection chamber which is partitioned off with respect to the ambient by a membrane which is permeable to the substance to be detected. The detection chamber is filled with an electrolyte which is subjected to changes in its characteristic under the action of the substance to be detected and these changes can be evaluated as electrical measured values via appropriate electrodes. The electrolyte contains a reagent which goes into an irreversible reaction with the substance to be detected and the dosimeter is improved so that after the evaluation it can be used again for measuring tasks or for collecting the substance to be detected. Furthermore, a calibration or a function test can be carried out on each dosimeter without its measurement readiness being limited thereby. A measuring electrode and a counter electrode are disposed in the detection chamber and are decoupled from each other with respect to a mass transport of the reagent as well as a reaction product formed from the reaction of the reagent with the substance to be detected. The reaction product can be converted quantitatively to a secondary product by a redox reaction at the measuring electrode by applying a voltage across the measuring electrode and the counter electrode.

摘要： The invention is directed to an electrochemical measuring cell for determining ammonia and its derivatives in a gaseous or liquid measuring sample. The measuring cell has at least one anode and at least one cathode which are disposed in an electrolyte chamber filled with a soluble electrolyte. The electrolyte chamber is closed off in the direction facing toward the measuring sample by a permeable membrane. The measuring cell provides a more selective ammonia sensor having the following advantages: a short response time, a linear response and exhibits the lowest possible tendency toward drift. The electrolyte of the measuring cell is so configured that the reaction products of the measuring reaction do not affect subsequent measurements. For this purpose the measuring cell, which operates in an amperometric measuring mode, contains a soluble non-oxidizable reagent in the electrolyte which reacts completely with ammonia to form an oxidizable product which is convertible by its oxidation into non-oxidizable soluble secondary products which are chemically and electrochemically inert.

摘要： The invention is directed to a measuring sensor for detecting gaseous components which operates in the diffusion limit current region. The measuring sensor includes a support body and has an electrolyte chamber partitioned by a diffusion membrane from the ambient containing the gaseous components. The measuring electrode of the measuring sensor is improved so that a simpler manipulation for covering the electrolyte chamber with a membrane is possible without endangering the mechanical stability of the membrane. During operation, the detection operation is intended to take place completely at that electrode surface which is in direct electrochemical exchange communication with the electrolyte supply. For this purpose, the coating is configured as an adherence joiner to the support body so that it forms an impermeable adherence region in the lateral direction between coating and support body. A process for producing the measuring electrode is characterized in that the coating is adheringly applied to a front face of the support body which forms a closed surface. Thereafter, a membrane layer is applied to the coating and a break through for communicating with the electrolyte chamber is formed in the support body by removing a portion of the support body starting from a rear face thereof lying opposite the front face. The break through is formed by removing the portion of the support body through to the coating. In the completed measuring sensor, this permits electrolyte from the electrolyte chamber to penetrate through the break through to the coating.

摘要： The invention is directed to an electrochemical measuring cell for detecting gaseous components with an electrolyte which is disposed between a counter electrode and a measuring electrode provided with gas permeable pores. The pores are configured as channels partially or completely filled with the electrolyte and these channels have a diameter which does not exceed 10 micrometers with a channel length of up to 300 micrometers and a web thickness of not more than 5 micrometers. With this configuration, drift and memory effects are suppressed and the measuring sensitivity is increased and, on the other hand, the response time and the residual current are reduced. When the measuring cell is used as a dosimeter, the counter electrode and the measuring electrode are decoupled with respect to a mass transport in the electrolyte.

摘要： The invention is directed to an electrochemical cell for measuring ammonia, amines, hydrazine and hydrazine derivatives and includes a measuring electrode in an electrolyte. The measuring electrode is provided with a coating made of a transition metal oxide and is improved in that its measuring sensitivity during long-term loading is increased. The cross sensitivity of the measuring cell is reduced especially with respect to NO.sub.2 and SO.sub.2. For this purpose, the oxide constituents of the coating are made of a metal conducting oxide of one element or an oxide mixture of several elements of the platinum metal group. Oxides of ruthenium and iridium have proven especially useful. The invention is also directed to an electrochemical measuring cell for measuring ammonia or hydrazine and includes at least a measuring electrode and a counter electrode in an electrolyte. The measuring cell provides a signal increase having a shorter response time and an improved signal stability. For this purpose, the electrolyte is an aqueous solution of a hygroscopic salt of an alkali metal or alkaline earth metal such as calcium nitrate or lithium nitrate or a mixture of both salts.

摘要： The invention is directed to an electrochemical measuring cell for detecting gaseous constituents in air. The measuring cell includes a measuring electrode and a counter electrode accommodated in a housing. The housing includes an electrolyte chamber and the electrolyte is in liquid contact with the electrodes. The measuring electrode is in diffusion contact with the gas constituents to be detected via a gas-permeable membrane which is impermeable to the electrolyte. The measuring cell is improved so that an effective pressure equalization between the electrolyte chamber and the ambient is made possible in the context of a simple assembly of the housing. For this purpose, the housing jacket surrounding the electrolyte chamber has at least one breakthrough. The electrolyte chamber is separated from the ambient by a gas-permeable stop disposed in the breakthrough. This stop is impermeable to the electrolyte.
