| Abstract: | The system for measuring CO 2,CH 4 and N 2O emissions consists of static sampling chambers,a modified Gas Chromatography(GC/Agilent 4890D)and an Agilent Chemstation.The modified GC with two detectors of FID and ECD was used to simultaneously detect the concentrations of CO 2,CH 4 and N 2O.Working principle,configuration and characteristic of the modified GC were presented.Results obtained from the GC/Agilent 4890D were close to those from the GC 14A.Field measurements conducted in Jiangning district of Nanjing City showed that the modified GC was convenient and suitable to simultaneously determine the emission fluxes of CO 2,CH 4 and N 2O from agro ecosystem. |
| Keywords: | gas chromatography paddy fields CO 2 CH 4 N 2O emission flux simultaneous measurement |
