APPLICATION OF A METHOD FOR MEASURING GAS OR VAPOR SUBSTANCES IN THE DETERMINATION OF THE CONCENTRATION OF ANESTHETIC GASES IN AMBIENT AIR AND DEVICE FOR SUCH APPLICATION

摘要

P A METHOD FOR MEASURING SUBSTANCES IN THE STATE OF GAS OR VAPOR, IN WHICH THE MODIFICATION, OR THE RATE OF MODIFICATION, OF THE ELECTRIC RESISTANCE IN A HEATED LAYER 5 OF A DETECTING SUBSTANCE CONTAINING DETERMINED PHTHALOCYANIN IS ADAPTED FOR DETERMINING THE CONTENT OF ANESTHETIC GASES, CONSTITUTED BY ORGANIC HALOGENATED COMBINATIONS, IN THE AIR OF A PREMISES. A DEVICE FOR THIS ADAPTATION INCLUDED IN THE AREA OF DETECTOR LAYER 5 PLACED ON A HEATABLE SUPPORT 1 AND CONTAINING PHTHALOCYANIN, A CATALYST 8 MOUNTED IN THE FREE AIR SPACE, BEFORE THE DETECTOR LAYER, FOR DISSOCIATION ANESTHETIC GAS MOLECULES TO BE DETECTED. /P
