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.

Introduction

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.
