| Zusammenfassung |
| We are presenting results from a mid-infrared laser-based Isotope Ratio Infrared
Spectrometers (IRIS) that is capable of simultaneously determining both δ18O and δ13C
isotope ratios of carbon dioxide utilizing a simple, direct absorption approach with a robust
multi pass cell and a cryogen free setup.
A simulation of ambient measurement conditions with a 75 ppm per hour change in CO2
concentration from 350-650 ppm showed a precision of |
