<p>An analysis electrode including a sensor on the sensitive surface of which a variable liquid flow has been applied into which the analysis substances diffuses through a semi-permeable membrane in connection with the electrode surface. By varying the composition and rate of the liquid flow it is gained, on one hand, that the analysis substance undergoes suitable modification, e.g., dissociation and, on the other hand, that the chemical environment around the sensor surface can be optimized, e.g. for an enzymatic reaction. In addition, the measuring range may be made variable by variation of the concentration of the analysis substance by changing the liquid flow rate.</p> |
