Simultaneous Analysis of Three Greenhouse Gas Components, CH4, CO2, and N2O


User Benefits

・The three major greenhouse gases, CH4, CO2, and N2Ocan be analyzed using GC-BID. ・They are simultaneously analyzed with high sensitivity by BID-FID series connection, a simple GC configuration. ・ECD, which requires complicated procedures, is not required.


In recent years, there has been a global demand to reduce greenhouse gas (GHG) emissions. To achieve “carbon neutrality,” a state of net-zero carbon dioxide emissions, innovative research and developments are ongoing in many countries. The major GHGs include methane (CH4), carbon dioxide (CO2), nitrous oxide (N2O), and chlorofluorocarbons, etc. The amount of CO2 emission is the largest, but the Global Warming Potential (GWP) of CH4 and N2O is 25 and 298 times higher than that of CO2, respectively. ECD is generally utilized to analyze N2O, but it is not sensitive to other GHGs and cannot be used for simultaneous analysis. Using a Dielectric-Barrier Discharge Ionization Detector (BID), most compounds, except helium and neon, can be detected with high sensitivity. In this article, simultaneous analysis of CH4, CO2, and N2O with gas chromatograph Nexis GC-2030 is demonstrated.
