Trace gas analyses

Important atmospheric trace gases are constituted by nitrous oxide (N2O) and methane (CH4).

 
Important atmospheric trace gases are constituted by nitrous oxide (N2O) and methane (CH4), which are strong greenhouse gases contributing to global warming. In addition N2O has importance for stratospheric ozone degradation. N2O and CH4 are detected in atmospheric air samples by gas chromatographic separation combined with Electron-Capture-Detection (ECD) for N2O and Flame-Ionization-Detection (FID) for CH4. Detection limit is ca. 30 nl per l of air.
