  • Title: An improved gas chromatography for rapid measurement of CO2, CH4 and N2O.
    Author: Wang YH, Wang YS, Sun Y, Xu ZJ, Liu GR.
    Journal: J Environ Sci (China); 2006; 18(1):162-9. PubMed ID: 20050567.
    Abstract:
    Combining improved injector, gas line and valve-driving modules, a GC equipped with FID and ECD, could simultaneously measure CH4, CO2 and N2O in an air sample within 4 min. Test results showed that the system has high sensitivity, resolution and precision; the linear response range of the system meets the requirement of in situ flux measurements. Thus, the system is suitable for monitoring fluxes of main greenhouse gases in terrestrial ecosystem since it is easy to use, efficacious, stable and reliable to collect data.
