Green House Gas Analysis
Green House Gas Analysis
Greenhouse gases are those that are found in the atmosphere that induce the greenhouse effect, which is an absorbance and emission of infrared energy emitted by the Earth. As sunlight strikes the surface of the Earth, some of the infrared light is reflected into the atmosphere. These greenhouse gases absorb that infrared energy and reflect it toward the Earth. This gas chromatograph system enables the easy qualitative and quantitative analysis of three major greenhouse gases: methane(CH4), carbon dioxide(CO2), and nitrous oxide(N2O).
