Simultaneous Measurements of H2O and CO2 Isotope Ratios using 2.73 µm Laser Spectrometer

Not Accessible

Your library or personal account may give you access


Simultaneous measurements of water and CO2 isotopologue ratios were performed using laser absorption spectroscopy in combination with Kalman filtering at 2.73 µm. The isotopic compositions of eH2O and eCO2 in breath gas were analyzed.
