Problems solved by technology

Since large volumes of measuring medium flow through such devices during long operating times, it must be taken into account that such sleeves become contaminated and clogged with solid and dissolved sample components or otherwise lose their usability, for example due to microbial growth

Embodiment Construction

[0063] figure 2 A longitudinal section through an ion-selective electrode 201 is schematically shown, which has a tubular housing part 202 with a closure cap 203 at one end and a connection with the tubular housing part 202 at the other end by means of a liquid-tight connection. The clapboard 215. Tubular housing portion 202, enclosure 203 and bulkhead 215 bound a housing cavity which is at figure 2 The example shown is completely filled with an ion-selective polymer membrane 205 . The sensing of the potential occurring on the diaphragm, the so-called diaphragm potential, is constituted as a stationary sensing without an internal electrolyte. A silver wire coated with silver chloride is used in this case as sensing electrode 213 . The ion-selective membrane 205 is in contact with the periphery of the ion-selective electrode 201 through the separator 217 on the separator 215 . During measuring operation, the housing part of the ion-selective electrode 201 with the partiti...

Abstract

The invention relates to an ion-selective electrode (201) comprising: a housing (202, 215) which surrounds a housing internal space, an ion-selective membrane (203), in particular a polymer membrane, and a sensing system which is in contact with the ion-selective membrane and is intended to sense a potential of the ion-selective membrane, wherein the ion-selective membrane at least partially fills the housing internal space, and is in contact with a medium, which surrounds the housing, via at least one hole (217) which passes through a wall of the housing.

Description

technical field [0001] The present invention relates to an ion selective electrode (ISE) having: a casing surrounding the interior space of the casing; an ion selective membrane, in particular a polymeric membrane, comprising at least one selectivity-providing component; An in-body sensing system for sensing the potential of a polymer membrane. Background technique [0002] Ion-selective electrodes generally refer to such electrochemical sensors in which the relative change in the equilibrium Galvani voltage between the measuring medium and the sensing electrode is preferably produced by a change in the activity of the predominantly defined ion type. Ion-selective electrodes of this type allow comparatively simple and rapid determination of ion concentrations in different media, for example also in turbid and colored solutions. Ion-selective electrodes are used, for example, in the analysis of process liquids or in the analysis of waste water. [0003] Potentiometric measu...
