Definitions
- a flow cell from Hewlett Packard is also known, which is also composed of a large number of individual components. Two highly planar parts, into which electrodes are integrated, are separated in a housing by a thin non-conductive film. A flow path for the transport of the liquid sample through the cell is omitted in the film, so that the internal volume of the flow cell is determined by the thickness of the film and the area of the recess in this film. The total height of this cell is approx. 9 cm.
- the electrode surfaces and previously the corresponding supply lines are applied to the upper and lower substrates using screen printing technology.
- the spacer is then applied by means of screen printing on the electrode side of at least one substrate provided with an electrode.
- there are two cell halves namely a substrate provided with an electrode and a further substrate provided with an electrode and the insulator layer.
- each cell half comprises a substrate provided with an electrode and a spacer.
- the two cell halves are then coated with an adhesive, for example a superglue, once on the surface of the electrode and that of the spacer, or on the surfaces of the two spacers, and pressed together for adhesive in order to obtain the complete cell.

Abstract
L'invention concerne des cellules électrochimiques à flux continu pourvues de capteurs à couches épaisses. La cellule électrochimique décrite comporte deux électrodes espacées l'une de l'autre et un canal d'écoulement situé entre ces deux électrodes, lequel est raccordé à une entrée et à une sortie. L'écarteur entre les deux électrodes est formé par une couche isolante réalisée à l'aide d'une technique à couches épaisses, un évidement plan de la couche isolante et l'épaisseur de cette dernière déterminant le volume interne du canal d'écoulement. Les électrodes sont ménagées sur des substrats et sont réalisées également à l'aide d'une technique à couches épaisses. La cellule est réalisée par collage de deux demi-cellules. De préférence, la couche isolante peut consister en un adhésif CMS non conducteur qui assure simultanément l'adhérence.
