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.
