Application of a method of measurement of substances in the state of the gas or steam at the determination of the concentration of gas anesthetics in the ambient air and a device for this application

摘要

A method of measurement of substances in the state of the gas or steam, in which will determine the magnitude of the modification, or the speed of modification, the electrical resistance in a layer of substance detector heated 5 containing the phthalocyanine, is adapted to the determination of the amount of gas anesthetics, constituted by combinations of organic halogenated, in the air of a local. A device for this adaptation has, in the region of the layer detector 5 mounted on a support heatable 1 and containing the phthalocyanine, a catalyst 8 mounted in the space of free air, in front of the layer detector, so that the dissociation of the molecules of the gas anesthetic has detection.
