description | The invention relates to a gas detection device and method. The gas detection device comprises a light-emitting assembly, an ionization chamber, a measuring chamber, a first detection assembly and a second detection assembly, the ionization chamber is configured to enable light emitted by the light-emitting assembly to be emitted into an ionization cavity, so that to-be-detected gas in the ionization cavity is ionized; the measuring chamber is provided with an outlet hole channel, and the outlet hole channel is communicated with the ionization cavity, so that the ionized gas to be measured flows out; the first detection assembly comprises a collecting electrode and a bias electrode; and the second detection assembly comprises a first electrode, a second electrode and a third electrode. The flow of the to-be-detected gas is controlled through the second detection assembly, the content of different components in the to-be-detected gas is measured according to the fact that the response sensitivities of the firs |
