采用气相色谱/燃烧/同位素比值质谱联用系统（GC/C/IRMS），建立了一种快速、简便的测定湿地气泡甲烷δ 13 C的方法。尽管甲烷不完全燃烧成CO2，但使用标准甲烷校准可提供精确度为±0.5‰的重复性数据。在20分钟内成功地测量了两个气体样品的重复分析。
A combined gas chromatography/combustion/isotope ratio mass spectrometer (GC/C/IRMS) system was employed to develop a rapid and simple method for measuring δ13C of bubble methane collected from wetlands. In spite of incomplete combustion of methane to CO2, calibration using standard methane can provide reproducible data with accuracy of ±0.5‰. Duplicate analyses of two gaseous samples were successfully measured within 20 min.
