Abstract

CE PROCEDE S'APPLIQUE A UN CAPTEUR COMPRENANT UNE ELECTRODE DE MESURE POLAROGRAPHIQUE 2 ET UNE ELECTRODE DE REFERENCE 5 ET SERVANT A MESURER LA PRESSION PARTIELLE DE GAZ DANS DES LIQUIDES DU CORPS HUMAIN, L'ELECTRODE DE MESURE ETANT MUNIE D'UNE MEMBRANE PERMEABLE AUX GAZ. IL SE RANGE DANS LA CATEGORIE DES PROCEDES D'ETALONNAGE EN DEUX POINTS, DANS LESQUELS ON PLONGE LES ELECTRODES RACCORDEES A UN DISPOSITIF DE MESURE DANS DEUX MILIEUX AYANT DES PRESSIONS PARTIELLES DE GAZ DIFFERENTES ET CONNUES. IL EST CARACTERISE EN CE QU'IL CONSISTE A PLONGER LE CAPTEUR MUNI D'UNE MEMBRANE D'UNE EPAISSEUR DONNEE DANS UNE SOLUTION DE MESURE EQUILIBREE EN GAZ POUR LEQUEL ON L'ETALONNE, PUIS A SOUMETTRE L'ELECTRODE HUMIDIFIEE A UNE PHASE GAZEUSE CONTENANT UNE CONCENTRATION DEFINIE DUDIT GAZ, JUSQU'A CE QUE L'APPAREIL DE MESURE INDIQUE UN MINIMUM. IL EN RESULTE UNE SIMPLIFICATION CONSIDERABLE DE L'OPERATION D'ETALONNAGE.THIS PROCESS IS APPLIED TO A SENSOR INCLUDING A POLAROGRAPHIC MEASURING ELECTRODE 2 AND A REFERENCE ELECTRODE 5 AND SERVING TO MEASURE THE PARTIAL GAS PRESSURE IN HUMAN BODY LIQUIDS, THE MEASURING ELECTRODE BEING EQUIPPED WITH A MEMBRANE PERMEABLE TO THE HUMAN BODY. GAS. IT RANGES INTO THE CATEGORY OF TWO-POINT CALIBRATION PROCESSES, IN WHICH THE ELECTRODES CONNECTED TO A MEASURING DEVICE ARE IMMERSED IN TWO MEDIA WITH DIFFERENT AND KNOWN GAS PARTIAL PRESSURES. IT IS CHARACTERIZED IN THAT IT CONSISTS OF IMMERSING THE SENSOR EQUIPPED WITH A MEMBRANE OF A GIVEN THICKNESS IN A GAS BALANCED MEASUREMENT SOLUTION FOR WHICH IT IS CALIBRATED, THEN SUBMITTING THE HUMIDIFIED ELECTRODE TO A GAS PHASE CONTAINING A DEFINED CONCENTRATION OF SAID GAS, UNTIL THE MEASURING EQUIPMENT INDICATES A MINIMUM. THIS RESULTS IN A CONSIDERABLE SIMPLIFICATION OF THE CALIBRATION OPERATION.
