Abstract

Abstract Translated from German Zur Realisierung einer strömungsgünstigen, kleinvolumigen Durchflußmeßzelle (4) einer Sensoranordnung zur Bestimmung einer Substratkonzentration in einem Probenmedium mit einer membran­bedeckten Enzymelektrode (13) und einer Referenzelektrode (23), welche mit der Meßzelle in Kontakt stehen, wird vorgeschlagen, daß die Referenzelektrode außerhalb der Membranabdeckung der Enzymelektrode (13) angeordnet ist und daß die maximale Ausdehnung der Durchflußmeßzelle (4) normal zur Strömungsrichtung des Proben­mediums im wesentlichen dem Durchmesser (26) der sensitiven Schicht (11) der Enzymelektrode (13) entspricht. In order to implement a low-flow, low-volume flow measuring cell (4) of a sensor arrangement for determining a substrate concentration in a sample medium with a membrane-covered enzyme electrode (13) and a reference electrode (23) which are in contact with the measuring cell, it is proposed that the reference electrode be outside the membrane cover the enzyme electrode (13) is arranged and that the maximum extension of the flow measuring cell (4) normal to the flow direction of the sample medium essentially corresponds to the diameter (26) of the sensitive layer (11) of the enzyme electrode (13).
