To provide a gas measuring apparatus capable of measuring the diffusion amount of the chemical substance diffused from a material placed at an arbitrary temperature or in an arbitrary atmosphere by irradiating the material with a light.
The gas measuring apparatus is equipped with a gas diffusing container 1, in which an object 5 to be measured is installed; a light irradiation means 2 for irradiating the object to be measured with a light; a shading means 3; a temperature control means 4 for controlling the temperature of the object to be measured; a gas supply means 6 for supplying gas to the gas diffusing container 1; a flow rate control means 7 for controlling the flow rate of the supplied gas and a gas collecting means 8, thereby collecting the diffused gas from the object to be measured, when the atmosphere, the temperature, the flow rate of the supplied gas and the like are changed and the object 5 to be measured is irradiated with a light.
