Abstract
A common method to estimate the carbon isotopic composition of soil-respired air is to use Keeling plots (d13C versus 1/CO2 concentration). This approach requires the precise determination of both CO2 concentration ([CO2]), usually measured with an infrared gas analyser (IRGA) in the field, and the analysis of d13C by isotope ratio mass spectrometry (IRMS) in the laboratory. We measured [CO2] with an IRGA in the field (n 637) and simultaneously collected air samples in 12 mL vials for analysis of the 13C values and the [CO2] using a
