Trace gas quantity analyses of CH4 (13C) and N2O (15N)

δ13C of CH4 and δ15N of N2O at ambient atmosphere concentrations are measured on a Thermo Scientific Precon connected to a Delta V plus isotope ratio gas spectrometer. The analyses need 100 ml gas or more at ambient concentrations. This is not currently a routine analysis at the lab. Please take contact for details.
