Abstract: The present invention relates to 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 2 and pCO 2 , the said calibration being carried out with at least one buffered solution containing O 2 , a known or tonometer-measured amount of CO 2 and known concentrations of the electrolytes and metabolites to be determined, in which calibration the pO 2 titre is determined beforehand using atmospheric oxygen as reference.
