Description

Technical Field

[0001] The utility model relates to the technical field of environmental gas analysis, in particular to an analysis device for greenhouse gases. Background Art

[0002] With global warming and increasingly serious environmental problems, the emission and control of greenhouse gases have become the focus of public attention. At present, for gas analysis, the gas is generally collected in a static box, and then low plants suitable for the box are placed in the static box. The growth status of the vegetation is observed and analyzed with the greenhouse gas in the box, and more accurate experimental data can be obtained.

[0003] However, when the gas enters the static box, it is in a flowing state, and dust impurities in the air will also be stored in the static box along with the gas. In this case, analysis and monitoring will obtain data with low gas cleanliness, and there is no comparable clean air. Although impure analysis data can be obtained, there are fewer comparable gas states. For this reason, we propose a greenhouse gas analysis device. Utility Model Content
