PURPOSE: To measure anesthetic gas in air by allowing radiant rays through a sample and then a filter for passing a wavelength corresponding to specific gases whose number corresponds to that of analysis gases and then detecting them with each detector. CONSTITUTION: Radiation rays from a radiation ray source 1 pass through a chopper 2 and enter a conical cell 3. The cell 3 has two transparent windows 4 and 5 and a gas mixture to be analyzed passes through an entrance 6 and is introduced and are discharged from an exit 7. Radiation rays from the cell 3 are reflected by a three-section mirror 8 and luminous flux 9 is divided into three partial luminous fluxes 9a-9c, are passed through each three filters 10a-10c, and are applied to three detectors 11a-11c. When measuring an anesthetic gas, CO2 detector is used for the detector 11a, N2 O detector is used for the detector 11b, and the detector for measuring anesthetic gas is used for the detector 11c. |
