Gasera one ghg greenouse gas analyzer offers reliable and simultaneous analysis of CH4 (Methane) and N2O (Nitrous Oxide) in ambient air. Many chemical compounds are present in Earth’s atmosphere and are capable of acting as greenhouse gases capable of absorbing and emitting infrared radiation emitted by Earth. Many of the gases such as carbon dioxide, methane, nitrous oxide and water vapor among others, occur naturally in the atmosphere and also have anthropogenic (man-made) sources. Methane (CH4) is the second most important greenhouse gas in terms of concentration and impact on the climate. Nitrous oxide (N2O) is also very potent greenhouse gas and a major scavenger of ozone.
