Abstract
A method for calibrating an instrument for the analysis of blood gases which possesses ion-sensitive electrodes and gas-sensitive electrodes and is used for the determination, in a biological fluid, of the concentration of electrolytes and metabolites in solution, and of the pH, pO.sub.2 and pCO.sub.2, the said calibration being carried out with at least one buffered solution containing O.sub.2, a known or tonometer-measured amount of CO.sub.2 and known concentrations of the electrolytes and metabolites to be determined, in which calibration the pO.sub.2 titer is determined beforehand using atmospheric oxygen as reference.
