I'd like to measure 13C/12C in CO2 in samples of soil respiration. Can the samples be directly forwarded via the PoraPlot GC column of GasBench to open split and mass spec? Or are any components of the air (e.g. molecular oxygen) prohibited from entering the mass spec and need to be separated out using the LN (cold) trap?
Any advice would be most welcome.
