Introduction to Gas Sensing Using Non-Dispersive Infrared ...

Carbon-dioxide infrared spectrum. Figure 3. Methane infrared spectrum . IR reacts with the gas only when a dipole on the molecule is created. Molecular dipoles can occur when the vibration modes are non-symmetrical or when atoms in the molecules are organized in a non-symmetrical fashion. The vibrations comprise bending and stretching of the molecules that deform them to produce dipole or ...

CO and CO2 – What’s the difference? |

CO - carbon monoxide and CO2 - carbon dioxide are often confused. While the names sound similar they are completely different gases with entirely different makeups. While both are colorless, odorless and tasteless gases and have the word "carbon" in their name they are not the same. The biggest difference is that CO2 is a common, naturally occurring gas found everyday from decaying plant and ...
