A sensor apparatus comprising a portable sensor body. The sensor body includes a support with one or more sensing electrodes, and electric connections connecting to the electrodes. The apparatus further includes a storage container, designed to receive at least a part of the support that includes one or more of the electrodes, for storing the sensor body. The container comprises a deformable wiper. The wiper is shaped correspondingly with the support and electrodes thereof, to wipe liquid (and/or other materials contained therein) off the support responsive to inserting the latter in the container and, conversely, responsive to de-inserting the support from the container. Mutually corresponding parts of the sensor body and the container may form a fastener, so as to be able to create a non-permanent joint between the sensor body and the container responsive to the sensor body being fully inserted in the container.

The invention relates to a closure for an electrochemical reaction vessel, in particular a potentiostat, the closure comprising: a holder for holding electrodes arranged at an inner side of the closure such that, when the closure is attached to a reaction vessel, electrodes held by the holder extend into an interior space of the reaction vessel and into an electrolyte contained in the reaction vessel; and a plurality of contacts arranged at an outer side of the closure for providing electrical contacts with the electrodes.

The present disclosure includes a method for determining the necessity of a measure and/or the success of a measure in the case of a sensor in a retractable assembly, comprising the steps: moving the sensor in the direction of a service chamber of the retractable assembly; analyzing an attribute associated with the sensor, wherein the attribute is a state of at least a portion of the surface of the sensor and/or composition of a medium in the service chamber; and deriving measures from the analysis. The present disclosure also includes a system comprising a retractable assembly having a sensor and a corresponding analysis device.

A method of forming a sensor, such as a glass electrochemical sensor, is described. In some examples, the method may include forming a plurality of apertures in a glass substrate; forming a sensor body comprising the glass substrate and at least one glass sensor component, wherein one or more apertures of the glass substrate are aligned with the at least one glass sensor component to form an outer contact aperture; filling the outer contact aperture in the sensor body with a first conducting material to form an outer contact through glass via (TGV); and forming an electrode on the glass substrate adjacent at least one of the apertures of the plurality of apertures.

Solid-state electrodes comprising Redox Active Surface Areas for use in analyte sensing devices and various product platform devices.

An electrode formed by molding a semiconductor device with resin. The electrode comprises: a first resin mold portion formed on a front surface of the semiconductor device and having a first thickness (t1); a second resin mold portion formed on a back surface of the semiconductor device and having a second thickness (t2) greater than the first thickness; and an exposed portion formed in a part of the first resin mold portion corresponding to an end of the semiconductor device.

A portable sensor includes a probe and a housing. The probe comprises a sensing part with one or more sensing elements, while the housing is designed to secure the probe such that the sensing part extends outside the housing. The portable sensor defines a gap between the probe and a surface of the housing that is configured to receive a rim of a liquid container such that the portable sensor can slot onto a rim of a liquid container, so as to allow hand-free measurements.

A system includes a body, a rod extending beyond a length of the body, a first cap at a first end of the body, and a second cap at a second end of the body. The first cap and the second cap are removably connected to the body. The system also includes a cup including an active material. The cup is located in the second cap. The system further includes a gasket between the cup and the body. The second cap exerting a force on the cup to press the cup against the gasket.

A gas sensor including: a sensor element extending in an axial direction; a metal shell surrounding and supporting the sensor element; an exterior tube that is tubular and is mounted to a rear end of the metal shell; a metal terminal including a first end connected to a lead wire and a second end electrically connected to the sensor element; a separator that is tubular and is disposed in the exterior tube and contains the metal terminal and the sensor element; and a holder being in contact with the separator in the axial direction. The holder includes ribs formed in a frontward face or a rearward face of the holder and arranged at predetermined intervals in a circumferential direction. Each of the ribs occupies a region having a length equal to or greater than a thickness of the holder, as viewed in the axial direction.

A multi electrode sensor that provides in-situ, real time measurements for molten salts and other process fluids such as real-time concentration and salt level measurements for nuclear systems such as molten salt reactors, nuclear reprocessing facilities utilizing molten salts and concentrated solar power systems. The sensor has multiple electrodes with unique lengths which are connected to a potentiostat. Measurements are taken when the electrodes are immersed in the process fluid.
