The calibration fluid is composed of a biocompatible electrolyte that, at 37° C., exhibits a concentration of bicarbonate ions that lies in the normal physiological range of the concentration of the bicarbonate ions of the blood, exhibits a pH value that lies within a pH value range within 2 through 13 containing the value 7.41 and has a specific ionic strength. In order to enable a calibration of the sensor with a higher precision compared to a known calibration fluid of this type both in vivo as well as in vitro, the ionic strength of the fluid at 37° C. is selected such that it lies in the normal physiological range of the ionic strength of the blood. |
