The inert gas is supplied from the inert gas supply tank 1 to the mass flow controllers 4, 5, 6, 7 via the flow path 2 and the branch flow path 3. The inert gas may be one that does not react with the odor component and the deodorant component, and examples thereof include air and nitrogen gas. The mass flow controller measures the mass flow rate, and unlike the volume flow meter, it can measure the flow rate regardless of the pressure, temperature, gas density, etc.,
It is suitable for use in the devices and methods of the invention, which are not necessarily open systems. The inert gas having a predetermined flow rate measured by the mass flow controller 7 is supplied to the mixing chamber 11 via the electromagnetic valve V7. Mass flow controller 4,
A predetermined amount of the inert gas whose flow rate is measured by 5 and 6 passes through the flow paths 8, 9 and 10 and the electromagnetic valves V 1 , V 3 and V 5 to the inert gas injection pipes into the sample bottles 12, 13 and 14, respectively. Fifteen, one
It is supplied via 6,17. In this description, including the figures,
Although the number of the mass flow controller and the number of the sample bottles are three for convenience of explanation, the number of the sample bottles and the like can be increased as needed. That is, one or more sample bottles containing an odor component-containing liquid and one containing a deodorant component are prepared in an appropriate number.

いる。The inert gas injection pipes 15, 16 and 17 open to the upper part of the liquid injected into the sample bottle, that is, to the gas phase part. The injected inert gas converts the gas phase odor component and the gas phase deodorant component which are in a gas-liquid equilibrium state in the gas phase portion, into the delivery pipes 18, 19, 20 provided in the sample bottles and the electromagnetic valves V 2 , V 4 ,
V 6 is transferred to the mixing chamber 11 via the flow paths 21, 22 and 23. By setting the gas flow rate of the inert gas within a range that does not impair the gas-liquid equilibrium state in the sample bottle, it is possible to obtain a mixed gas of each gas-phase odor component and gas-phase deodorant component with good reproducibility. . The electromagnetic valve is installed to shut off the flow of the inert gas, the gaseous odor component and the gaseous deodorant component, and to prevent backflow.

を進める働きがある。The mixing chamber 11 is provided with a member (not shown) for stirring and mixing gas inside. As a member for stirring and mixing a gas, for example, a static mixer, a fractionating tube and the like can be mentioned. Examples of the fractionation tube include a Vigreux column, a rotating band type fractionation tube, and a packed tower. An inert gas is supplied to the mixing chamber 11 via the mass flow controller 7 and the flow path 24. The supplied inert gas increases the amount of the mixed gas discharged from the mixing chamber 11 and makes it easier to reach the nose of the gas-phase odor component and the gas-phase deodorant component, that is, the nose, or the analyzer. Further, the inert gas has a function of increasing the gas flow rate in the mixing chamber, thereby promoting turbulence and promoting the mixing of each gas-phase odor component and each gas-phase deodorant component.
