    Abstract: The present disclosure relates to a method for manufacturing a sensor cap with at least one main body and a membrane for an optochemical or electrochemical sensor for determining and/or monitoring the concentration of an analyte in a measuring medium, a corresponding sensor cap, and a corresponding sensor. In one aspect of the present disclosure, a permeable membrane is provided with a surface for contacting the measuring medium, as well as a main body with at least one sector for connecting to the membrane. At least part of the membrane and main body are welded, wherein the membrane is at least partially applied to the at least one sector of the main body and a connection between the main body and membrane is sealed against the measuring medium.

    Abstract: An electrochemical method for analyzing the presence of certain analytes in a fluid in concentrations as low as parts per trillion without use of reagents. This is done by using a combination of filtration, microfluidics, increasing the electrochemical gradient, while reducing double layer capacitance, the Nernst layer and other methodologies discussed below. Such a method can be used to get data on certain pollutants like heavy metals in real time and then through internet of things send the data to the Cloud. Such a methodology would help form a nervous system for the planet, wherein pollutants are monitored in real time.

    Abstract: In order to provide a reference electrode capable of suppressing an error in a measured value even when refilling an internal solution during sample measurement, a reference electrode including: a casing adapted to store the internal solution in an internal space; and an internal electrode that rises from the bottom surface of the internal space and is immersed in the internal solution further includes: a surrounding wall that rises from the bottom surface so as to surround the side circumferential surface of the internal electrode; and an inlet port that is for refilling the internal solution in the casing. In addition, in the reference electrode, the surrounding wall is adapted such that a fore end surface thereof is opened and the height thereof is higher than the height of the internal electrode, and the inlet port is adapted to be opened toward a space outside the surrounding wall.

    Abstract: The present disclosure discloses a method for producing an ISE half-cell, including the steps of: immersing a first end of a hollow body into a membrane solution comprising at least one solvent and an ion-specific ionophore; removing the hollow body from the membrane solution; drying the hollow body and evaporating the solvent from the membrane solution, whereby an ion-selective membrane is created at the immersed end of the hollow body; and completing the hollow body to make an ISE half-cell. The present disclosure also discloses an ISE half-cell that is produced according to such a method. The present disclosure further discloses a sensor and a multiparameter sensor comprising several such ISE half-cells.

    Abstract: A potentiometric sensor having: a measuring half cell with a conductor element; a reference half cell with a reference element; a measuring circuit that is connected with the conductor element of the measuring half cell and the reference element of the reference half cell, is designed to create a measuring signal that is dependent on a potential difference between the conductor element and the reference element. The measuring half cell further includes: a housing, in which a housing chamber is formed, which is closed off by a first ion-selective membrane and contacted by the conductor element a first inner electrolyte contained within the housing chamber, contacting the ion-selective membrane, wherein the conductor element includes an inner conductor, especially an inner conductor comprising a metallic conductor, that is connected with the measuring circuit and a gas-tight barrier separating the inner conductor from the first inner electrolyte.

    Abstract: An electrochemical oxygen sensor includes a sensing surface having a working electrode and a reference electrode, a hydrophilic layer formed from an oxygen diffusion-limiting layer emulsion overlaying the working electrode and a hydrophobic membrane formed from a hydrophobic solution disposed over the hydrophilic layer. The hydrophilic layer contains an epoxy network and a hydrophilic polymer. The hydrophobic layer contains an acetate copolymer and a cross-linking agent that reacts with the liquid epoxy resin in the hydrophilic layer forming the epoxy network where the hydrophobic member is water vapor and oxygen permeable.
