Infrared

Explanation

Absolutely, each IR-active gas molecule possesses a distinct absorption spectrum. This implies that each molecule selectively absorbs energy at specific wavelengths, resulting in a unique "fingerprint" for that particular substance. The absorption is directly related to the energy portion of the spectrum associated with a specific wavelength. By detecting the wavelengths and the extent of their absorption, we can gather two crucial pieces of information. Firstly, we can determine the presence of a specific gas within a composition based on its characteristic absorption pattern. Secondly, we can quantify the amount of that gas present. Our sensor operates in the 2 to 15µm region of the electromagnetic spectrum, which is advantageous because many gases exhibit characteristic absorption in this wavelength range. This enables our sensor to identify and quantify a wide range of gases based on their distinctive absorption patterns within this specific region of the spectrum.
