Description

Technical field [0001] The invention relates to a gas detection device, in particular to a formaldehyde detection device and a detection method. Background technique [0002] Formaldehyde is a colorless gas with a special irritating odor, which has a stimulating effect on human eyes and respiratory system. Living in an environment containing formaldehyde for a long time will cause great harm to the human body, so the accurate measurement of formaldehyde concentration is of great significance. The measurement of formaldehyde gas in the prior art mainly adopts spectrophotometry, electrochemical method and chromatography, etc. However, the above methods have low detection sensitivity, and the detection response speed is slow and the content of formaldehyde in the air cannot be obtained in real time. Therefore, how to design a formaldehyde gas detection device with high sensitivity and fast response speed is the technical problem to be solved by the present invention. Summary of th...
