description | The invention relates to a method for collecting gas in an automobile cabin for evaluating odor in an automobile, and belongs to the technical field of in-automobile odor evaluation. The method comprises the following steps: manufacturing a closed low-adsorption container; a conduit is arranged on the closed low-adsorption container; a valve is arranged on the guide pipe; a pressure gauge is also arranged on the closed low-adsorption container; air is completely pumped out from the guide pipe, and a closed low-adsorption container in a vacuum state is obtained and placed in an automobile cabin; collecting gas in the automobile cabin into a closed low-adsorption container; the pressure gauge is observed, when the reading reaches a pressure threshold value, the air pump is stopped, and the valve is closed; a closed low-adsorption container sent to a smell evaluation laboratory is communicated with the sampling bag through a guide pipe; and the valve is opened, and the gas is automatically injected into the samp |
